The gray mass of the ICO projects: PR-a course and no revolution

The gray mass of the ICO projects

The gray mass of the ICO projects: PR-a course and no revolution


If you are not the first time you hear about ICO-projects, then you will understand exactly what will be discussed in the future. How often are ICO projects that are ready to change our usual world, arranging a technological revolution? Unfortunately, this does not happen often, and not because of the presence of serious technological developments in ICO projects, but rather because of simple speculation over the value of the startup.

ICO projects

Without a doubt, blockchain is a useful development that is already creating a fundamentally new society of the future. Technology is needed right now, and it proves its value. It is universal and applicable in many areas. But it is important to know that the blockchain itself is not a "cure for all diseases".

With the development of the market and the emergence of new ICO projects, competition is growing, and every startup wants to be what is called "the next big thing"abroad. Nevertheless, in a ridiculously large number of cases, developers do not chase an achievable and tangible goal, but pursue a spirit of innovation, trying to apply the blockchain system to everything, even in cases where it looks frankly ridiculous. We will not jump to conclusions, but if such ideas can help our society in the future, then either the market is too niche for them, or the "revolutionary" system of brave businessmen is inapplicable to the current realities and is doomed to failure.

There are a huge number of such ICO projects. Therefore, this article describes only some of the" revolutionaries " of the blockchain industry, whose mission is real, but not practical. Each of them in its own way pushes the idea of changing the world for the better in a variety of areas, but not all of these areas need to be applied to them blockchain technologies. In order to avoid conflicts with the creators of the presented ICO projects, their names were hidden. Perhaps some projects readers will still be able to learn.

Opens our ICO-project list, positioning itself as a global platform for entertainment, combining streaming concerts and performances, social network and its own cryptocurrency. Although the plans of this ICO project stretch very far, now its main goal is the industry of Korean pop idols. Users will be able to book tickets for their concerts, pay for their appearance in various talk shows and advertisements, buy merch and participate in crowdfunding campaigns of artists. Popular words like "full transparency"are included. The only question in this case-why to the already huge industry to fasten the fifth wheel in the form of blockchain? Perhaps the technology needs to produce a "revolution" in the industry of Korean pop idols associated with their forgery. As a result, the capitalization of the project reached $90,000,000.

Continuing the theme of social networks with" unnecessary " technologies of decentralization, we come to the next secret candidate. This ICO project is a service, the cornerstone of which is selfies. The more photos the user publishes, the more cryptocurrency he gets. The earned money can then be spent on various offers from brands cooperating with the company. All anything, but it is doubtful that social networks with one root feature can compete in the market where in this sphere there are already giants, especially even those giants are not insured against possible collapse as we could already see on the example of Vine and Musically. The idea of gamification and promotion in such networks is certainly interesting, but it can be achieved without the blockchain factor, and the oversaturation of the market with such applications does not guarantee success. It should also be noted that the introduction of the blockchain itself is quite expensive: both technologically and financially. In the first case, the problem of scalability and system protection immediately appears. In the second case, there is a difficulty in increasing the payback time of investments.

From social networks on the blockchain, we are moving to another, similar "revolutionary" ICO-project. In it, developers aim to revolutionize the blockchain, simplifying it specifically for the generation of Millennials with their own crypto-wallet and social network, which helps to learn about things happening in the world of crypto-trading. Of course, this seems like a good goal, but only until you look up the dictionary meaning of the word "Millennial". Most of the representatives of this generation are more than twenty or even thirty years old. Almost all of these people have long decided what they need from life, and if they are passionate about the world of blockchain, they already understand many aspects of it and they do not need to find a special service for their generation (which in itself is strange). What is the point of making a special "revolutionary" blockchain for Millennials — remains a big question. There is no doubt only one thing — this project looks like Steve Buscemi in the outfit of a cool student from "Studio 30".

The next ICO project is exclusively for women. Undoubtedly, from the point of view of marketing, it attracts attention with loud statements like "raising awareness about cryptocurrencies among women", but such PR tricks can hardly really increase women's interest in this cryptocurrency. And goals like "become the number one altcoin for women in business" every day seem to cryptocurrency more and more ghostly. The moral here is that it is necessary to concentrate on real women's problems, and not try to fight the mythical "inequality" in the crypto-sphere.

And since we have smoothly switched to attempts to insert the blockchain into real world problems, we will consider a new ICO project that calls for the fight against global warming. Its essence lies in the use of native cryptocurrency for certain contributions in support of different species of animals that are threatened with extinction as a result of climate change. There is only one catch: why do you need your own cryptocurrency? The fight against global warming is a very difficult process that requires cooperation at all levels and in all countries, and it can not be solved by creating a special cryptocurrency. It is strange to believe that this particular cryptocurrency will be in demand by conservationists when there are such kings of crypto-transactions as Ethereum or Dash. That is why the ideas of this "revolutionary", although they carry an important meaning, are unlikely to be truly implemented.

We are moving from climate change to the fight against the shadow economy in prisons. One project offers a revolutionary method of dealing with it-partial legalization and use of blockchain. Of course, it will be very good if prisoners can spend more and legally establish a transparent system of exchange of things and goods in prisons. However, it does not take into account the factor that speculation in prisons can not be completely stopped: it is doubtful that the ICO project provides for the sale of drugs, files and sharpening in its system, but such things will always be in demand in prisons, and partial legalization of trade will not help the situation. Surprisingly, the project currently has a capitalization of about $ 1,250,000.

All considered projects confirm the words said at the beginning of the article that everyone wants to become the "big thing". The immaturity of the blockchain market means that it will try to apply to a variety of areas, even if they do not get along in principle or will not get along in the current realities. It is a disease of every nascent industry. Suffice it to recall the market "Dot Com", when the online store was screwed to any kind of goods without a clear demand for its purchase via the Internet. The Internet has become a part of us in just 20 years.

At the same time, there are really promising projects, and such diversity is by no means a bad thing — every ten shitcoins make one really good project Shine with new colors.

The main thing is to follow the development of the ICO project product, not its marketing, and then it will be easier to find your "unicorn" of the crypto-industry.

BurstCoin (BURST) - cryptocurrency with explosive prospects!

BurstCoin (BURST) - cryptocurrency with explosive prospects!

BurstCoin (BURST) - cryptocurrency with explosive prospects!


It is clear that anyone reading this article, at least, knows about the existence of bitcoin and Its many followers-forks. If you are a little more immersed in the topic, then no doubt you know that most of these forks hardly deserve your and our attention. Basically, it is a pale copy of the" big brother " Bitcoin, not shining with novelty and originality.

But, fortunately, not everything is so sad and unambiguous. As in the piles of rock there is no-no, and the gold bar will Shine, and in the pile of alternative crypto-currencies from time to time there is a development with which you want to get acquainted closer.

One of these rare finds we want to share with you today. This digital currency, the authors called modestly, but with a certain message – BurstCoin, which can be translated as a flash or explosive coin. But no matter how you translate, and there are certain expectations-it seems something bright and impressive. How true such associations, time will tell, and now let's get acquainted with this "flash" in more detail.

What is the "explosive coin" Burst?

BurstCoin (BURST) - cryptocurrency with explosive prospects!


This is both a cryptographic coin and a payment system, which is based on blockchain technology. Given the rapidity of development of cryptosphere, this coin is not particularly "young". It appeared in the late summer of 2014. The launch was not preceded by any premine or IPO.

The currency itself is a fork of NXT because it is based on the source code of this particular crypt, but it would not be worth talking about if it did not have a fundamental difference from its predecessor. And there is such a difference. In BurstCoin is the first time in the history of cryptoprocta used a new mining algorithm Proof of Capaciti (PoC, or proof of capacity).

The essence of mining on the POC algorithm


This type of mining, as we have already noted, is fundamentally different from the well-known methods of mining the crypt. It is crucial to have free space on your hard drive, and your willingness to use it to "dig" currency. It will depend on the profitability of the work. However, some role play and processing power, and RAM, but only at the stage of preparation.

The first thing to do is to install a wallet. You need to install the current version of the" wallet " Burst, and also note that for its functioning you need Java. At the end of this stage, you will receive the address of your new "purse", which will "drip" money.

Your next step is selection of the pool and check on it, that cost is likely 1 coin Burstain (you throw someone from colleagues in the forum), then you will be entered in the number of recipients. Solo mining is also available, but as mining becomes more difficult, it becomes less profitable.

Then you need to collect the plot (a set of data calculated by the miner and stored subsequently on the computer's memory). Just this stage involves the use of the processor. Well, now you can start working directly. The main advantage is that in addition to the computer you do not need any more "iron", and the disk subsystem is loaded moderately enough, which has a positive effect on the energy efficiency of production.

Then everything is simple and familiar – go with your coins to the exchange and change to dollars or BTC (that's how you like it).

As you can see, there is nothing complicated in mining on the hard drive. To get started you need to go through a few simple seven steps:
  1. Download and install BurstCoin wallet.
  2. Registration of the personal account.
  3. Enter the passphrase (key).
  4. Login to your account.
  5. In the menu at the top left, you will see the number of your wallet, which you need to write down, as well as the cells at the bottom of the window (Write slots).
  6. Wait for the system to finish generating data.
  7. Select blocks and pool, and get started by clicking on "Start".

HDD selection criteria and a few examples of suitable hard drives

BurstCoin (BURST) - cryptocurrency with explosive prospects!


The equipment in cryptocurrency mining takes an important place and you need to be able to choose it correctly. In our case, we are talking about choosing a decent hard drive. The first thing you need to pay attention to is the ratio of cost and memory, in other words, you need to estimate how much you will cost 1Gb of memory. It is clear that the cheaper it is, the more profitable it will be for you.

The second criterion is the reliability of the device. However, this indicator is quite relative, because the HDDs produced today differ little in quality. Below we give a few suitable in our opinion options.

There are quite a few affordable and quality options brand Toshiba – DT01ACA Series 2TB, 3TB DT01ACA Series 3TB HDWD130UZSVA and P300. The first model is ideal for mining crypts, the cost of one Giga of memory is about 2.4 cents, but for a truly productive farm will need a lot of hard drives.

The second model proved to be good, the cost of 1Gb is only 2.3 cents. And the third option is also different efficiency (2.4 cents per 1Gb) and good performance.

I would also like to note the model Archive HDD ST8000AS0002 8TB from Seagate. It is noteworthy that the unit of memory is worth about 2.35 cents, while the usual cost of such memory in the hard drives on 4-6 TV is not below 2.7 cents, which makes them economically not very profitable. And another option with the cost of 1GB of memory only 2.3 cents – Seagate BarraCuda ST4000DM005 4TB.

BurstCoin cloud mining

The fact that there is such a method of mining cryptocurrency know, perhaps, all.


The fact that there is such a method of mining cryptocurrency know, perhaps, all. But, basically, they know about the services that provide cloud mining services for Bitcoin and some other well-known digital coins. We want to introduce you to a resource that allows you to mine unfamiliar and not quite ordinary coin Burst.

Called service Burstmine and its services it offers is not very expensive. As you know, since this crypt is extracted on hard disks, Burstmine offers users free space on disks, and the power is not measured in Tera, Giga and Megahashes per second, but in Tera and Gigabytes.

Advantages and disadvantages of POC-mining burstcoin

Advantages and disadvantages of POC-mining burstcoin


Any method of mining the crypt has its attractive sides and disadvantages. The algorithm we consider is no exception.

The advantages clearly include the fact that you can do without cumbersome and expensive equipment, no need to spend time and money to find suitable graphics cards (built-in enough). The system is simple enough to install and configure, and placed all in the ATX-case of your computer. Moreover, you will not need any powerful power supplies, because a dozen HDD consume only about a hundred watts. In addition, they are not as hot as video cards (the heat generated by one gaming graphics card is comparable to the heat produced by a dozen hard drives). As a result, you will not need noisy and powerful cooling systems. And, finally, with this method of production of crypto-coins, it is not necessary to be a cool professional and thoroughly understand all this computer "hardware".

With the advantages it seems to be finished, it's time to talk about the shortcomings. They are not so much, but to know them will be quite useful.

The first and perhaps the most significant drawback is a fairly limited list of cryptocurrencies that can be mined in this way. The second thing to be warned about is the complexity of implementing a used hard drive. If you suddenly decide to update it, it is not the fact that you can return at least part of your costs (for example, used video card is much easier to sell). I also write about this moment, as the likely failure of the HDD after not very long, but in our opinion, is pure the reassurance of a series of "what if". Of course, anything can happen, but we would not classify such a probability as obvious shortcomings.

BurstCoin is a digital currency that turns "smart" contracts into reality


Attention to digital currencies has recently been focused to a large extent due to the possibility of using blockchain technology in the development of smart contracts. The number of startups launching "smart" contracts (like Ethereum) is multiplying every day. By tracking such large projects, the community almost missed a seemingly inconspicuous startup that was actually able to get ahead of everyone else in this matter.

Of course, we mean the Burst project, which launched a coin that allows you to produce smart contracts directly from your wallet. These very contracts can radically change many aspects of our lives. Up to the point that over time we will be able in many cases to do without lawyers or bankers, as intellectual contracts are able to fulfill the terms of contracts automatically.

The plans of the developers BurstCoin to increase the number of supported smart contracts, low, to 10 and to support online games, Autonomous corporations, etc. Such developments will make possible the implementation of instant transactions when conducting crowdfunding, auctions, lotteries and many other occasions when the need arises.

Conclusion burstcoin


The BurstCoin project is attractive, first of all, by the availability and simplicity of creating and running a mining farm. But this is for those users who are focused on mining. And in General, it is much wider than the usual concept of cryptocurrencies, it has prospects in the field of intellectual contracts, for which the future. So we advise you to look at this site for those of you who want to use blockchain technology in your business, whether it's business, creativity or some other field of activity. Good luck!

A new breakthrough in cryptocurrency scalability

A new breakthrough in cryptocurrency scalability

A new breakthrough in cryptocurrency scalability


The research team has introduced a new scalability solution that will allow 17,000 transactions per second on the Ethereum network.

17 000 transactions per second Ethereum promises a breakthrough in cryptocurrency scalability


Researchers Ethereum Harry R., Yeongdong Fu, Philip Castonguay, Alex and the fantastic Barry Waythat recently introduced a sidechained. This is a new scalability solution outside the Ethereum blockchain based on Snark.

The method will allow you to transfer tokens and ether outside the network at a transaction speed of up to 17,000. This speed can sravnits indicator Visa. If developers manage to implement the solution, it will allow blockchain and cryptocurrencies to move to a new level.

In late September, the founder of Ethereum offered to scale Ethereum with the help of ZK-SNARKs technology, which was originally used in the ZCash network.

"We can significantly scale transactions for the transfer of assets in the Ethereum blockchain without second-level solutions (channels, Plasma), using zk — SNARK for mass transaction validation," Vitalik Buterin wrote.

Also yesterday, the network reported that the co-founder of Blockstream mark Friedenbach came up with a method of scaling the first cryptocurrency, which does not require a hard fork. The specialist describes the scaling method, according to which the sharding technology can increase the volume of transactions by 3584 times compared to the current level and improve censorship resistance.

Do we need the blockchain in medicine?

Do we need the blockchain in medicine?

Do we need the blockchain in medicine?


Blockchain technology has significantly changed the financial market. Decentralization, immutability, transparency look attractive for other spheres of life. To date, several projects have introduced blockchain into the health care system. We will tell you how blockchain is used in medicine and what potential it gives to companies that care about our health.

Blockchain capabilities in medicine


The main characteristics of the blockchain are applicable and useful in the field of medicine. It is only necessary to assess the potential and gradually implement projects on the blockchain in this area. We present several significant changes that are possible in medicine with the introduction of blockchain technology.

Control


Facilitate control over the supply of narcotic drugs and counterfeit drugs.

Falsification of medicines cannot be avoided even with full state control over the pharmaceutical industry. At the moment, the amount of falsification is from 15 to 80%. The certificate of authenticity of the means can be easily forged.

Blockchain will track the path of the drug from the manufacturer to the retail pharmacy. This will make the pharmaceutical industry fully controlled. In theory, any drug will become controlled.

You can enter additional functions — monitoring the availability of medicines in clinics, and the opportunity to see the transfer of drugs, their number etc on the packing need the barcode, which is a special application will make the data on the blockchain.


Immutability



The database in the chain cannot be changed or deleted. This makes it impossible to falsify medical history. The patient controls access to their data. It can provide them through the app to a specific doctor or medical organization.

Currently, when going abroad, the patient is a secret for doctors. For example, if the patient needs surgery, you need to know the reaction of his body to anesthesia. This can only be found out from the patient himself. But the patient can forget, be unconscious, incapacitated or a child. There is a problem that is easily solved thanks to the application based on the blockchain, where all the information is stored.

You can also get reliable data about the patient and his medical history. This is required by various fields of activity, where necessary information about the physical and psychological health of the person.


Insurance



The introduction of a special API in medicine will facilitate and secure the transfer of patient data between organizations. This is especially true in the field of insurance. The information can be used by insurance companies with the consent of the client. Thus, any of us will be able to provide access to medical records in exchange for the insurance service. Currently, all data is reported by the client. The insurance company either believes in the word, or should independently recheck the information.

Real blockchain projects in medicine


Dentacoin


The Dutch Foundation for Dentacoin Foundation released the currency to the world dental industry. The idea of the project is that patients pay for services and goods with tokens. The Foundation relies on the fact that dental services will become more accessible. This will increase the percentage of preventive examinations, reduce the number of dental problems in need of treatment. In the near future it is planned to create a single database based on the blockchain.

MediBloc


Decentralized health information ecosystem for patients, medical and research organizations on the blockchain. The project allows:

To collect information about treatment to the doctor, getting treatments and medications.
To integrate information about the client in different organizations. As a result, the patient receives quality medical care, rapid diagnosis, personalized approach.
Have access to the database in real time.
Medishares
Decentralized currency based on Ethereum blockchain. It is aimed at using life insurance services within the platform. The insurer freezes funds to pay for services in smart contracts. The client applies to the platform to receive these payments. The project is still under development.

Lympho


A healthy lifestyle ecosystem that collects information about a person's health and lifestyle and records it on the blockchain. The essence is that the client always has at hand all the information about himself and can use it in medical institutions, health sports complexes. The system of promotion and remuneration, monitors the results of the client and monetizirovat his healthy lifestyle. LYM coins are used for the purchase of sports and medical goods, health care services.

Timicoin (TMC)


Open source cryptocurrency. Used as payment on TimiHR. It is a decentralized platform for sharing information about the client's health. Currency is a reward for those customers who provide information about themselves to medical organizations. It is possible to buy goods and receive medical services.

In contrast to the financial sector, health care is more cautious about new technologies, as it is one of the most controlled and conservative industries. The introduction of new technologies is always associated with the infusion of a large amount of additional funds.  To exchange data about patients, even within a country needs to develop a network and learn new skills staff. These factors slow down the involvement of blockchain technology in medicine.  However, even the limited implementation of the distributed register has potential in the future.

10 facts about the blockchain, you don't want to believe

10 facts about the blockchain, you don't want to believe

10 facts about the blockchain, you don't want to believe


Despite the fact that everyone is talking about the blockchain, many have the wrong idea about the possibilities and purpose of this technology.

Even in 2017, the excitement around the blockchain was just huge. People believed that this technology would affect all sectors of the economy, change the face of our planet and simultaneously bring millions to investors in ICO.

All this hype has led some to believe in completely crazy ideas about the blockchain and its capabilities. Many people have the wrong idea about the potential of this technology — they consider it something that it is not really.

Blockchain is just a database with some distinctive features. It allows multiple users to record and share information in real time, with the parties not having to trust each other as the correctness of the records is controlled by the participants receiving the reward in the form of tokens/coins. These features are very specific and really useful only in certain circumstances.

For example, they are perfect for cryptocurrencies like bitcoin — its blockchain allows you to send money to anyone in the world with minimal costs without the need for a Bank or other intermediary.

However, block chains are not really suitable for storing all types of data and certainly should not be used to solve far-fetched problems.

Today we will talk about 10 common myths about the blockchain and its applications (like bitcoin) both from haters and from ardent enthusiasts.

1. Bitcoin isn't the biggest Scam in history, it's not rat poison, and it's not dead


In 2017, against the cryptocurrency were some well-known financiers, including Warren Buffett, Charlie Munger and the head of JP Morgan Jamie Dimon.

Yes, blockchain and bitcoin based on it — like any new revolutionary technology-have their drawbacks. The proof-of-work consensus mechanism consumes huge amounts of electricity; cryptocurrency is actively used for speculation and illegal activities.

But to say that this technology is going to fail is like saying in 1995 that the Internet will not work because it is clumsy and unorganized.

Bitcoin lives and lives for 10 years, although he has repeatedly predicted the death. At first glance it may not seem credible, but says Navale Ravikant:

"Bitcoin is a tool for liberating humanity from oligarchs and tyrants, served as a scheme of rapid enrichment."

Concentrating on the shortcomings of this technology and calling bitcoin a Scam, we completely forget about its advantages and potential.

2. Blockchain will not increase the value of your company's shares


Kodak, Long Island Iced Tea and on-line Plc are excellent examples of using the hype around the blockchain to raise the value of shares. At the same time, none of the companies has anything to do with technology.

3. The blockchain is not a pyramid scheme


Although the financial pyramid on the basis of this technology meet. For example, PonziCoin is a typical Ponzi scheme (and don't mention Bitconnect).

4. Cryptocurrencies are not just for scammers


There have been many cases where investors and companies have suffered from break-ins and scams. This is a big problem for the industry, but not a sentence. It is anonymity-one of the main advantages of the blockchain — that allows hackers and scammers to go unpunished. But this is an unpleasant side effect of the technology, not its task.

Terrorist groups like ISIS (banned in Russia) are looking for recruits on social networks, but this does not mean that we should abandon Facebook and Twitter.

Pablo Escobar was so rich that he burned American dollars to warm his daughter. The entire drug industry is held solely on cash. Does that make them bad?

5. Blockchain is not intended for fundraising


The fact that some unknown company attracted millions of dollars during the ICO does not mean that its behavior should be copied.

The purpose of the ICO is not only to raise funds, but also to distribute tokens between potential users of the project. Ultimately, they must perform a function. If the startup has nothing to do with the blockchain, then the need for tokens disappears. They should not be used for banal fundraising.

6. Blockchain will not change your business


If the company does not have a real need for the advantages that the blockchain can offer, it is better not to communicate with it and store data in the old way.

7. Blockchain will not change absolutely all industries


Heard the phrase"it's like Uber for (a certain industry)"? It's funny, but it even penetrated the blockchain ecosystem. Some companies are literally trying to create Uber on the blockchain.

A small problem with this venture is that not every industry needs blockchain. Let's say you don't like Uber's attitude towards employees, and instead of switching to Lyft, you're inventing a blockchain solution?

"Decentralized, peer — to-peer taxi service" sounds really cool. But this idea completely ignores all the shortcomings of the blockchain.

By definition, there is no Central authority managing the public blockchain. Who will make decisions in such a company? How about dispute resolution? Once the data has been loaded into the block chain and validated, it cannot be changed. Paid for a trip you didn't take? The driver behaved disgustingly and it needs to be reported? Alas, you are not lucky, because there is no one to complain.

What about development? How will a distributed company without executives compete with one of the richest startups in history with a well-established market share?

Even if a decentralized Uber can overcome all the problems and create a working service, how much better will it be? Uber and other similar centralized apps are already working quite well. The alternative will probably fail to exceed them.

The potential benefits of moving many existing industries to blockchain are not high enough for users to decide to change their habits.

8. The blockchain is not intended for sacrifices of Cthulhu


We will just leave this link here and not go into details.

9. Blockchain is not a platform for memes


10 facts about the blockchain, you don't want to believe
Dogecoin is the most famous cryptocurrency-meme. It was created on the bitcoin code base in 2013 as a joke, but this did not prevent its capitalization from growing to $ 2 billion last year.

10. Blockchain is not useless


Unless, of course, a token based on it was created intentionally.

So what is blockchain?


We have listed all the cases for which the blockchain is not suitable. Now it is time to talk about the scope of its potential application. The blockchain will fit perfectly into the project that needs:

  • Distributed and immutable database;
  • Supports multi-user recording;
  • Does not require trust between the parties;
  • Able to eliminate unnecessary intermediaries;
  • Able to provide consensus and verification.
  • Money fits perfectly into this category. Cryptocurrencies such as bitcoin meet the above criteria and are perfectly compatible with the blockchain.

Unfortunately, at the present time there are not so many other areas that are suitable for mass application of the blockchain. This does not mean that they will never be — we just have not found them yet.

Summing up, we can say that blockchain is a useful technology, but it is not a Savior of business, economy or humanity. We all need to know the true potential of this technology and understand what it can actually achieve.

2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years

2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years

2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years


What fate awaits the current market leaders, if only two of the top 10 cryptocurrencies of 2013 could remain in the list?

Since its birth in 2009, bitcoin has dominated over other cryptocurrencies. Over the years, his example has led to the emergence of numerous altcoins, whose trends, value and value were determined by the dynamics of the oldest and most famous cryptocurrency.

May 26, 2013 on the website CointMarketCap was only 15 cryptocurrencies. Their total capitalization slightly exceeded $ 1.5 billion.

Forbes magazine called 2013 the "year of bitcoin". In that year, the cryptocurrency won the hearts of many investors, hit the headlines and was ahead of the price of gold, reaching a price of $1,242 per coin.

The interest in bitcoin has jumped. Thematic conferences, forums and seminars have started to be held. Some considered cryptocurrency a Scam, others-a promising and attractive project. The truth is that both positions were surprisingly convincing. And-due to the high volatility of the crypto currency in the following years, the attitude towards it was constantly changing.

Here's what the top 10 cryptocurrencies looked like in 2013 — and in what condition they are today.

1. Bitcoin


2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years
On January 3, 2009, Satoshi Nakamoto received the first 50 bitcoins (Bitcoin) for generating the Genesis block. In subsequent years, his brainchild has experienced many UPS and downs and is still famous for its extreme volatility, high risk and resistance to interference of the authorities and financial regulators.

In 2013, the total value of bitcoin was $ 1.477 billion, and it still remains the largest cryptocurrency with a capitalization of $ 114 billion.

2. Litecoin


2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years
Peer-to-peer cryptocurrency is open source, allowing instant payments to any country in the world. Litecoin was founded on October 7, 2011 by former Google employee Charlie Lee. Surprisingly, just 24 hours after the start of trading, the value of the cryptocurrency soared twice. In November 2013, its market capitalization has reached $ 1 billion. However, then the second place in the list was taken by another project, Ethereum.

Currently, the capitalization of litecoin (LTC/USD) is 3.4 billion dollars; it is on the seventh position in the list of the largest cryptocurrencies.

3. Namecoin


2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years
Namecoin is another cryptocurrency based on the Proof-of-Work consensus algorithm. It is distinguished by separate data storage in the blockchain. Namecoin appeared on April 18, 2011 after a preliminary discussion at the Bitcointalk forum, which started in December 2010. In may 2013, the total cost of Namecoin was 5.3 million dollars.

In July of the same year, it was hacked and the reputation of Terracoin was destroyed. Hackers managed to increase the speed of network hashing and put it under control.

Today, Terracoin is on the CointMarketCap 730th place, and the sixth position in the list of the largest cryptocurrencies from Stellar with a capitalization of 4.6 billion dollars.

7. Devcoin


2013 vs. 2018: how the top 10 cryptocurrencies changed in 5 years

In 2013, the cryptocurrency of the list of the top 10 were of great interest, however, only two managed to stay in it in 2018. Digital currencies suffer from FUD (fear, uncertainty and doubt) and FOMO (fear of missing out on your chance). FUD has a strong negative impact on projects, spreading rapidly through forums and social networks.

The future of cryptocurrencies depends on regulation in different countries. We will have to be patient to find out which cryptocurrencies will be among the winners and achieve mass recognition.

Pampa auf Yobit endete. Die Börse wählte PutinCoin

Pampa auf Yobit endete. Die Börse wählte PutinCoin


Wer will nicht schnell und einfach Geld verdienen? Sie hatten die Gelegenheit, genug an der Pampa an der Börse Yobit teilzunehmen (darüber haben wir auf dem Kanal geschrieben). Und obwohl die offizielle Windel einer zufälligen Münze Wut und Verurteilung in der kryptokomunition verursacht hat, konnte jemand immer noch gut aufsteigen.

Diesmal Börse wählte Münze PutinCoin. Es ist In der coinmarketcap-Rangliste, wo es 1083 Platz mit einer Marktkapitalisierung von 161 tausend Dollar einnimmt. Wir werden bemerken, dass der Präsident der Russischen Föderation nichts mit der kryptowährung zu tun hat.

Pump it!


Die Geschichte stammt aus dem 11. Oktober. An diesem Tag erschien auf dem offiziellen Twitter-Account Yobit Informationen über die bevorstehende Pampa zufallsmünze an der Börse. Viele nahmen die Nachricht als Witz auf, aber die Vertreter des tauschers hatten ziemlich ernste Absichten.

Das» Opfer " der Pampa war die PUT-Münze (PutinCoin). Während 10 Minuten kaufte die Börse eine bestimmte Anzahl von Münzen im Wert von 1 BTC. In dieser Zeit wurde 10 BTC für den Windeln ausgegeben. Das Ergebnis-PutinCoin stieg um 1400 Prozent (von 118 auf 1768 Satoshi). Darüber hinaus sind die Handelsvolumina der kryptowährung in nur 40 Minuten auf 130 BTC gestiegen.

Alles, was scharf nach oben zieht, sollte genauso dramatisch fallen. Es scheint das Grundgesetz der kryptoindustrie zu sein. Nachdem Yobit aufgehört aufzukaufen PutinCoin, Kurs Münzen entlud sich in nur wenigen Minuten.

Wie auch immer, Yobit schaffte Es, die Marke von 28 Millionen US-Dollar an Handelsvolumina zu überwinden. Höchstwahrscheinlich verwendet der Tauscher nicht mehr zum ersten mal solche Taktiken. Früher wurde das Management der Börse wegen versteckter Windeln von Münzen angeklagt. Laut einer unabhängigen Studie ist Yobit der bevorzugte Ort für altcoins-Machenschaften. Vielleicht wird die Börse in Zukunft weiterhin» offiziell " zufällige kryptowährungen kaufen.

Der Weg nach oben: 12 überzeugende Gründe, dass Ethereum wachsen wird


Ethereum ist eine sehr vielschichtige Plattform, deren Aussichten praktisch Grenzenlos sind. So glaubt Lane Rettig, Gründer von CRYPTO NYC. In seiner jüngsten Veröffentlichung auf Medium führte Rettig 12 Beweise, dass für Astraleums alles gerade erst beginnt. Das Gespräch wird nicht über die Marktkapitalisierung oder den Preis der Münze gehen. Der Experte achtet nur auf die grundlegenden Faktoren - das Wachstum des kryptowährungs-ökosystems und seine Anwendung.

Grund #1: alles geht nach Plan


Astraleums Roadmap wird allmählich in die Realität umgesetzt. Sharding, Casper, Ewasm und andere Verbesserungen sind nicht mehr nur eine Theorie, sondern ein fast fertiges Projekt. Die einzelnen logischen Blöcke sind gebildet, und das Ethereum Foundation-Team beendet die Arbeit an kleinen Details.

In letzter Zeit haben sich viele talentierte und vielversprechende Persönlichkeiten den Entwicklern angeschlossen. An Der Schaffung von Proof-of-Concept Ethereum 2.0 arbeiten Teams mit guter Finanzierung.

Ich werde eine kühne Aussage machen: es gibt keine unüberwindlichen Hindernisse für Entwickler.

Die Skalierung des Astraleums ist nur eine Frage der Zeit.

Grund # 2: Maker funktioniert


Nicht nur Tether kann uns mit steeblecoins versorgen. Dies gelingt auch dem Maker-Projekt, auf dessen Plattform das Dai-Token veröffentlicht wird. Sein Preis entspricht einem Dollar. Zwischen USDT und Dai gibt es einen wichtigen Unterschied — Dai wird von Ethereum-basierten Smart contracts bereitgestellt, während Tether von der Währung in einer zentralen Organisation unterstützt wird.

Wie hat Maker in einem Bärenmarkt überlebt? Das Projekt verwendet einen Mechanismus für gesicherte schuldenpositionen (CDP) und andere externe wirtschaftliche Anreize. Während all dies funktioniert, funktioniert es dezentralisiert. Wir werden erinnern, Tether im letzten Jahr hat es geschafft, viel Lärm wegen Gerüchten über die unvollständige Sicherheit von USDT-Tokens zu verursachen.

All dies funktioniert auf der Grundlage von Astraleum. Investoren interessieren sich allmählich für Maker und genießen Dai als Ersatz für Tether.

Grund # 3: Brieftaschen sind noch besser geworden


Viel, viel besser. Denken Sie nur, was wir vor einem Jahr hatten und was wir jetzt haben: Coinbase Wallet, Wallet, Trust Wallet, Cipher Browser und Status. Die Schnittstellen der Geldbörsen werden ständig aktualisiert, so dass unerfahrene Benutzer viel einfacher sind, die Prinzipien der Weiterleitung von kryptowährungen zu verstehen.

Jetzt ist es bereits möglich, den Balance Manager herunterzuladen, bald wird es auch viele andere interessante Anwendungen für die Speicherung von Astraleum geben. Die gleiche Wallet Connect verfügt über einen opensorstandard, mit dem Sie Mobile Wallets mit einem PC verbinden können.

Grund # 4: Loom Network


Im Juni startete das Team sein erstes Projekt namens Plasma Cash, das es ermöglichte, ERC-721-Token auf Loom-Seiten zu verwenden. Jetzt hat das Startup ein vollständig funktionierendes Zombie Battleground-Spiel, das auf der Grundlage der Plasma-Implementierung funktioniert. Das Kartenspiel wäre ohne Astraleums unmöglich, viele Spieler werden es nicht einmal erraten!

In ZB präsentiert ein sehr vielversprechendes marketingmodell-Entwickler haben es geschafft, müde in-game-Käufe zu vermeiden. Stattdessen haben Sie ein Provisionssystem eingeführt, das den Spielern noch sehr gefällt. Statistiken sprechen für sich selbst-die Anzahl der aktiven Nutzer Zombie Battleground über 100 tausend.

Grund # 5: Entwicklung neuer Ethereum-Kunden


Mehrere Kunden wurden in den letzten Monaten veröffentlicht: Nimbus, Pegasys und Lighthouse. Alle von Ihnen wurden von Profis in Teams mit guter Unterstützung und Finanzierung entwickelt.

Jede dieser Ideen hat Ihre eigenen Eigenschaften. Zum Beispiel ist Nimbus für Mobile Geräte optimiert, und Pegasys hat eine vollständig modulare Struktur, die in Java läuft. Mehr Entwickler und Forscher werden dem Prozess der kundenerstellung beigetreten, was bedeutet, dass wir schließlich mehr Dezentralisierung in Ideen, Roadmaps und Baga-Resistenz erhalten.

Grund # 6: stacking bringt Geld


Das Konzept des stacking für eine Person, die weit von der kryptowährung entfernt ist, sieht ziemlich lächerlich aus, als wäre es «Geld aus der Luft zu schaffen». In der Tat hat das Thema ein enormes Potenzial.

Ich habe Mehrere livepeer-Token an den Transcoder delegiert. Der gesamte Prozess dauerte nur ein paar Momente, und dann kann man die Token für eine Weile vergessen. Nach 102 Runden steaking (etwa 13 Wochen) bekam ich 11,82 LPT Gewinne. Das sind 189 Prozent des jährlichen Gewinns.

In Bezug auf die Wirtschaft wird das steaking-Einkommen mit der Ankunft neuer Menschen in die Industrie allmählich sinken. Wenn Anleger jedoch mehr Auswahl in steaking-Projekten haben (einschließlich Ethereum selbst), wird dieser Prozess eine ausgezeichnete Alternative Altersvorsorge für Millionen von Menschen sein.

Grund # 7: Entwicklung des Konsenses innerhalb von Ethereum


Es ist schwierig, ein so großes Projekt zu verwalten, aber in den letzten Monaten haben wir einen großen Schritt vorwärts in dieser Angelegenheit erlebt. Entwickler haben es geschafft, einen Konsens über mehrere EIPS zu erreichen, den blockpreis zu reduzieren und die Details des Constantinople hardforks zu diskutieren. Es gibt weiterhin Diskussionen über die Stabilität des Ethereum-Netzwerks gegen ASIC-Mining und die änderung des Proof-of-Work-Algorithmus.

Vor dem hintergrund seiner «Konkurrenten» sieht Ethereum sehr gut aus. Bitcoin-entwicklervereinbarungen sind in das auftreten von fast nutzlosen Gabeln (und Bitcoin Cash) gegossen. EOS erlebt auch nicht die besten Zeiten-das Projekt hat ernsthafte Probleme mit der Dezentralisierung.

Grund # 8: Bildungsressourcen


In diesem Jahr hat der junge Entwickler Karl Flores den Cryptoeconomics-Service geschaffen.study, die einen kostenlosen vollständigen Open-Source-Kurs bietet. Und in der Zwischenzeit erscheinen Hunderte von interessanten Materialien über blockchain auf Blockgeeks.

Andreas Antonopoulos wird bald Mastering Ethereum veröffentlichen, das auch opensorisch sein wird. Wenn Sie eine eigene DApp erstellen möchten, gehen Sie einfach zu Den chainshot-Kursen, hier können Sie die Solidity-Programmiersprache selbst lernen. Die spielerische Variante des Kurses ist in Ethernaut vom Zeppelin-Startup verkörpert.

Darüber hinaus wird das lernen von Krypta und blockchain allmählich auch in den Top-Bildungseinrichtungen der Welt eingeführt.

Grund # 9: Entstehung von Fonds


Fonds für Ethereum-basierte Investitionen erscheinen noch schneller als Sie sich vorstellen können. Traditionelle Möglichkeiten, Risikokapital zu verteilen, haben ernsthafte Konkurrenten: Stable Fund, ECF, Status Incubate, EF grants, ETHPrize und Aragon Nest.

Der Prozess der Investition durch diese Projekte kann langsam sein, aber es verbessert sich jeden Tag. Es ist auch erwähnenswert, die Bounties-Systeme von Gitcoin und Bounties Network.

Grund # 10: DApps finden praktische Anwendung


Das Ethereum-ökosystem kann endlich einige Orte ersetzen, um die traditionellen Web2-Anwendungen und Dienste, die wir jeden Tag nutzen, zu ersetzen. Slack, GMail, Twitter und Reddit haben bereits dezentrale alternativen.

Natürlich, während diese DApps wie Spielzeug Aussehen. Sie haben begrenzte Möglichkeiten, und nicht viele Menschen nutzen Sie jeden Tag. Dezentrale Anwendungen haben jedoch ein enormes Wachstumspotenzial in der Zukunft.

Grund # 11: funktionierende mikrozahlungen


Im Rahmen des Dienstes beginnt SpankChain ein funktionierendes ökosystem zu schaffen. Das Entwicklungsteam verbessert das Projekt weiter und schreibt ständig Informationen über den Fortschritt der Updates im Medium. Sie haben eine eigene Website mit Live-Streaming, Chat und micropayments auf Basis von Ethereum erstellt.

Kürzlich hatten Sie ein eigenes System zum stapeln von SpankBank-Tokens, und bald werden die Projektteilnehmer in der Lage sein, Token an der internen Börse zu handeln. SpankChain löst das eigentliche Problem, mit dem Modelle in der Erwachsenen-Entertainment-Industrie konfrontiert sind. Früher wurden Ihre Bankkonten oft wegen unbestätigter Einnahmen eingefroren. Jetzt können Sie anonym und sicher verdienen.

Grund # 12: Astraleums Gemeinschaft


Community kryptowährung nahm mehrmals für dieses Jahr. Um dies zu sehen, nur zu einer Vortragsveranstaltung EthCC oder хакатоны ETHGlobal und ETHBerlin. Unity ist mehr als nur Technologie. Es erwirbt alle Anzeichen einer völlig unabhängigen sozialen oder sogar politischen Bewegung.

Wenn in absehbarer Zukunft immer noch «der Mörder des Äthers " erscheint, ist es unwahrscheinlich, dass er in kurzer Zeit die Popularität und Wertschätzung seines Konkurrenten erreichen kann. Die Ether-Einheit besteht aus Missionaren und nicht Söldnern. Nun, und noch ein paar Regenbogen und Einhörner.

Bank of America named 9 companies that will earn billions on blockchain


The market associated with the introduction of blockchain technologies is able to grow to $7 billion.the Mass use of innovative technology makes it possible to repeatedly improve its financial position to high-tech giants and major players in the real estate market.

The large-scale introduction of the blockchain will provide an opportunity for large high-tech corporations to earn billions, says an analyst at Bank of America Kash Rangan.

The expert suggested that at some point in the future 2% of the existing corporate servers will run on the blockchain. If we take into account that the operational maintenance of only one such server will be $5,500 thousand per year, the total volume of the blockchain technology market can reach $7 billion.

The potential beneficiaries of the implementation of distributed registry technologies are such companies as Amazon, Microsoft and Oracle, the analyst noted.

"Amazon will benefit from the introduction of blockchain from the demand for cloud services, while improving the efficiency of supply chain tracking will improve Amazon's retail trade," the CNBC expert quotes.

Also, the analyst of Bank of America mentioned the Microsoft Azure platform, which is a catalog of solutions and cloud services ready for rapid automatic deployment. The technology giant can offer users the BaaS blockchain model, i.e. a ready-made business model from the cloud based on innovative digital technology.

Such well-known in the FINTECH industry companies as Oracle, IBM, Salesforce.com and VMware is also able to capture its share of the emerging market. In addition to high-tech giants, great prospects to earn on the development of the blockchain appear among the major players in the real estate market and mortgages. The expert identified three companies in this sector: Redfin, Zillow, and LendingTree.

Revolution in the field of mining


The monopolist of the mining market Bitmain is folds

Found a competitor-the firm Bitewei, which was founded by Yang Zosin, once a leading engineer Bitmain.
The monopolist of the mining market Bitmain is folds

Bitmain was at risk


Now Cosin controls BitWei Technology Co., Ltd. and intends to market (in conjunction with Pangolin) modern ASIC miner WhatsMiner M10 (M10 ShenMa) on the basis of 16нм-technoprogressive. His competence has already helped to optimize the performance of 16-nm chips WhatsMiner M10 so that the ergonomic performance they are not inferior to 7nm-processes.

"Bitmain then vaguely imagined what I was going to work on next, they were not aware of the details. These were next-generation designs that were different from anything I had created earlier, working on the S7 and S9. Probably, it is difficult to try to optimize, improve and implement other people's developments without knowing the original idea of the Creator. Technology is not static, it is constantly evolving. It is due to the fact that Bitmain was not able to realize this process in time, The company has not presented any competitive innovations in the field of mining since then," the developer said.

After zoxing left the giant company, He decided to start his own project.


"In order for the new company to reach the same scale and achieve the same impact as Bitmain, It will need to prove the performance of its business model and resistance against all the pitfalls of the market. It does not hurt and just luck. It is difficult to conquer the mining market, especially when there are only 4 million bitcoins left to be mined," said Obelisk Manager David Warwick.

However, Bitmain will not be so easy to win. The Chinese company still holds the palm. The world's largest manufacturer of equipment for the extraction of digital currencies after the pre-IPO reached a capitalization of $ 15 billion. This happened in August this year.


Mining Investors go to HDD Mining


Investors of the company were the largest co-owners of Uber-Japanese Softbank and Chinese IT giant Tencent. The latter is the developer of the popular platform in China WeChat. It has more than 1 billion users and is ahead of Facebook in terms of capitalization.

An IPO is due to take place soon, and the shares of the mining giant will be placed on the Hong Kong stock exchange. The company hopes to reach $ 30 billion. Earlier, representatives of Bitmain reported 1 billion net profit for the first quarter of this year. Earlier, the manufacturer completed a series b financing round, after which the company's value rose to $ 12 billion.
