1. Is it possible to cancel a BTC transaction?

As already mentioned above, unfortunately, it is not possible to cancel the transaction in the Bitcoin network technically and physically. In the history of the coin, many users, on their own bitter experience, were convinced of this feature of digital currencies. At first glance, this may seem to be a developer’s fault, but if you recall the blockchain technology, which underlies cryptocurrencies, then everything falls into place. The fact is that Bitcoin is a decentralized system, that is, it does not have a single center from which it would be possible to correct the direction of transactions. It is worth noting that cryptocurrencies gained their popularity precisely for the opportunity to exchange coins without the control of intermediaries.

You can see the transaction queue, but you cannot return the funds. Transactions in digital currencies are different from traditional electronic systems. The process of conducting transactions consists in rewriting the balances of two wallets (the sender’s and the receiver’s). Data about this operation is written to the registry, after which it is no longer possible to change it.

2. Why is it impossible to return Bitcoins?

Due to the peculiarities of the technology, it is not possible to reverse the transaction. If You, for example, bought something on the Internet and paid bitcoin, but want to make a return of the goods, then You need to contact the seller to make a new transaction to Your wallet. Since the data on Your payment has already been successfully entered in the register and nothing can be done about it.

But what to do if You accidentally sent money to the wrong wallet? Let’s be honest, unfortunately, you have to put up with it, since most likely you will not get it back. Although the Bitcoin address, to which the transaction was made, is in the public register, there is no possibility to find a person by name or surname. Therefore, You cannot 100% know of whom you have sent your digital assets.

3. The transaction isn’t responding, what should I do?

A long time of confirmation of transactions in the Bitcoin network is the weak point of this payment system. The BTC algorithm is designed in such a way that it can handle only 7 operations per second, so sometimes users have to wait for the transaction to complete for several hours or even days. But it happens that they hang for a very long time, for what reasons can this happen?

  • a sudden break in the Internet signal;
  • setting a too small commission fee.

What should you do in this case?

  1. First, you need to make sure whether the operation is actually suspended or whether the queue has just not yet arrived. Open Block Explorer, it will be indicated there.
  2. Next, go to the debugging console (Help-Window-Debug-Console);
  3. Get a private key from your wallet.
  4. Export private access keys to all bitcoin addresses, on which there are funds.
  5. After that, close the application and delete the wallet.
  6. Again run the client of the wallet program, create a new wallet and import private keys. Prepare that this process will take a sufficient amount of time.
  7. Done. In the new wallet, access to blocked funds will be resumed. In this way, you can undo an unconfirmed Bitcoin transaction.

It is important to understand that this instruction does not apply to cloud wallets.

4. Conclusion

Performing transactions on the Bitcoin network one should be extremely careful, since they cannot be reversed. This is both the main feature and the lack of the system.

Facebook Is Once Again Looking for Blockchain Specialists

Being a social media giant, Facebook could not turn a blind eye to blockchain. It actually launched a whole department devoted to the research of this technology and was looking for a manager for this department some time ago.

However, none of the representatives of Facebook have revealed any detail as to what they are planning to do with blockchain, which caused a wave of rumors starting from the assumption that Facebook is going to release its own cryptocurrency to the one claiming that Facebook was working on a blockchain network, planning to outrun Ethereum.

The truth is still unclear, but the fact is: Facebook is definitely working on something. It has listed 5 vacancies for blockchain developers on its official site. Considering the fact that it is Facebook and also the rate of salaries for blockchain specialists, there surely will be a huge fight for these 5 jobs. We remind you:

TV series adviser Brian Stoeckert, expert in risk management and anti-money laundering, in the interview with CNBC said:

“People have heard about digital currency, but they really don’t understand how it operates. They just see it on the headlines,this is one way they can follow a story line and get a unique perspective on it”.

2. Mr. Robot

Sam Esmail created not just an American psychological TV show, but the whole iconic picture, which consists of 3 seasons. The serial is highly appreciated by programmers and those, who are interested in innovations.

In one of the episodes, the president of E-Corp or “evil corporation” Philipp Price (the actor Christopher Michael) and a high-ranking official, whom serial fans compare to Jacob Lew, discuss the future of their cryptocurrency and Bitcoin.

“The problem here is hard cash is fading, rapidly, this is the way of the world right now and Bitcoin is spreading and it Bitcoin takes of the wheel all in a world of hell. It is unregulated,it’s already reached its transaction volume maximum and it is part plate control by Chinese miners”.

3. The Big Bang Theory

Popular comedy series, which wins our hearts with edgy sense of humor and thin sarcasm. Many believe, that the target audience of sitcom are just “techs”, since its main characters Leonard Hofstadter and Sheldon Cooper, who were played by Johnny Galecki and Jim Parsons respectively, are talented physics. Nevertheless, the humour doesn’t revolve around the science and the characters get into quite familiar situations for everyone.

The series creators were inspired by cryptocurrency so much, that in 2017 they have devoted the whole episode to it under the name “The Bitcoin Entanglement”. In the serie, the main characters recalled, that they had mined BTC and saved them on a Flash-drive, which was lost 🙂

4. The Simpsons

Also in the 7 serie, season 25, Bitcoin was depicted on the billboard near the school:

5. Almost Human

You must admit, that it would be weird if a science fiction TV show, events of which develop in 2048, didn’t concern Bitcoin. The creator, J. H. Wyman, wouldn’t make such mistake. True, Bitcoin in the series, is not what we are used to “not seeing”. Here, the first cryptocurrency of nowadays is presented in the form of a large flash drive.

6. The Blacklist

The cryptocurrency has not fully replaced the fiat and a certain percentage of humanity doesn’t even understand what it is. But, others are already bringing clarity to the public about the digital currency. The writers,of “The Blacklist” decided not to invent a new cryptocurrency, but to use the well-known Ripple.

Andreas Antonopoulos Does Not Think Bitcoin Is in a “Death Spiral”

With the current downtrend of Bitcoin and the crypto market in general, a lot of crypto experts and enthusiasts do not see any bright future for #1 digital coin. The infamous prediction of John McAfee now seems even more far-fetched than before.

However, some people still have faith in BTC. A famous author of books about cryptocurrency and blockchain Andreas Antonopoulos made a video where he explained what a death spiral is and why it does not relate to Bitcoin so far.

According to Antonopoulos, a death spiral arises when the hashrate of the network drops.

Since it is directly connected with the mining complexity, the complexity also reduces together with profitability, causing miners to leave.

However, the author believes this is not the case with Bitcoin, since BTC miners do not react to such price jumps immediately. Their plans are usually calculated for the long-terms results. Only if Bitcoin keep dropping for a significant period of time, the danger of a death spiral may appear.

Part of the reason that’s unlikely to happen is that miners have a much more long-term perspective, meaning that they have existing investments in equipment and they usually purchase electricity on long-term plans, they don’t pay it by the week,” says Antonopoulos.

Hopefully, the crypto author is right, because if miners start leaving the ecosystem of Bitcoin, the coin is doomed.

SWIFT Created A New Payment System To Protect Blockchain and FinTechs Provided By Ripple, JP Morgan, and Transferwise

SWIFT has announced in its latest press-release that it decided to launch a new payment service – Global Payment Initiative (GPI), which is still in pilot version. The system is aimed at combating threats that bring harm to blockchain and other fintech solutions of such institutions like Ripple, JP Morgan, and Transferwise.

The main target of the pilot is “to build the foundation of a new integrated and interactive service that will significantly improve efficiencies in the payments process and which will ultimately be made available to all 10,000 banks across the SWIFT network.”

The GPI tests were conducted in October to try cross-border payments with banks in Thailand, China, Australia, and Singapore. The trial showed that using GPI-system payments could be carried out almost instantly.

According to SWIFT, the pilot GPI system starts working in the first half of 2019. It will cooperate with 15 financial institutions, including Bank of China, JP Morgan, CitiGroup and others. The service provides full transparency to payment beneficiaries and originators.

Bitcoin’s Price in 2019: Forecasts and Opinion of Experts

Attention of many people around the world is focused on the Bitcoin price. No one can say for sure, where it will go next year, or moreover in a few years. Some people believe, that the cryptocurrency industry has already reached its maximum, and all that we are waiting is a continuous decline of value. But there are experts who are sure that the maximum marks of BTC is only beginning and we are expecting for the new heights in the future. Well, let’s try to look into the matter and analyze the words of leading financial experts of the world.

1. Analysis of the current situation

As we all remember, the capitalization of the cryptocurrency market reached its historic maximum 831 billion dollars in January 2018. After this, a deep and prolonged correction has started, which partially continues until now. At the time of writing, the market capitalization is 107 billion dollars, the Bitcoin price has fallen in 6 times, and many coins have become cheaper in 10-20 times.

At first glance, everything seems to be bad and prospects are rather vague. But what if we tell you that everything is absolutely opposite and now it is the best time to invest in cryptocurrency? We are ready to back up our words with concrete facts about which very few people talk. 

  • Continuous growth of network`s hashrate. Despite the fact that the price of first cryptocurrency shows negative profitability throughout 2018, the total computing power of Bitcoin network is constantly growing. It means that miners are increasing their production capacity. And it is not about small or medium farms, since their share is negligible on the general background.

After analyzing this graph, it appears that big miners continue to invest hundreds of millions dollars in equipment. This means that major players continue to believe in further development of the industry, and therefore in future growth of the BTC rate.

  • Infrastructure development. In 2018, investor`s interest in cryptocurrency faded a little, but this did not affect infrastructure development. Every day, the number of places where you can pay with cryptocurrency is growing (paying taxes in the USA, real estate, online shopping, transport tickets, physical points of sale and more). It is a very good trend, because the more places you can pay with BTC, the more people will be involved in the digital economy.
  • The acceptance of cryptocurrency at the government level. In 2018, for the first time in 10 years of Bitcoin’s existence, they started talking about it at the international level. If earlier none of the world leaders paid enough attention to this topic, then this year at the G20 summit this issue was put on the agenda. World leaders agreed that it would be pointless to forbid cryptocurrencies and no one would do that. On the contrary, there was decided to develop an international legislative framework.
  • It’s still possible to become a “pioneer”. If you go to the website bitinfocharts.com and take a look how many Bitcoin wallets are registered currently, it is possible to see the number that does not exceed 23 million. Taking into account that more than 15 million of them are wallets, which balance does not exceed $100. The population of our planet now is about 7.6 billion people. Let’s take 40% of insolvent people (children, pensioners, people who live in a third world, etc.) – it comes out near 4.5 billion people. After comparing these numbers, it appears that there are still very few people who are really involved in the cryptocurrency industry. That means, a global large-scale acceptance of technology does not exist yet. This gives us a chance to become pioneers. After cryptocurrency becomes a commonplace for any person (like, for example, a credit card in our days), we will reap the benefits. Most likely you will hear such expression in future: “Why didn’t I buy Bitcoin in 2018?”.

2. Expert forecasts for 2019-2020

Now let’s see what famous experts say about the near future of Bitcoin, namely about its price.

Mike Novogratz, CEO of Galaxy Digital, believes that the start of Bakkt and Fidelity Digital Assets platforms will affect on entry of new investors into the cryptocurrency market. According to Mike`s opinion, now the most important point of resistance is the mark of $ 3,880. If we overcome it, then the rate may reach $ 9,000 till the new year. The next important mark is $10,000. After overcoming it, the price of BTC 2019 will go up sharply. Novogratz has no doubt that the next year rate of Bitcoin will overcome its historical maximum of 20,000 dollars.

Tom Lee, is one of the leading analysts of Wall Street. Previously, he stated that until the end of 2018, the rate of Bitcoin will overcome the mark of 25 thousand dollars. But after a few months, namely in July 2018, he slightly revised his views and named the new price of Bitcoin 2019 – 22 thousand dollars.

The forecast of John Mcafee is the most bravest of all existing on the market. He believed that by December 2020, the price of one bitcoin will be $1,000,000. Moreover, John is confident in his forecast like no one other. In his view, in the upcoming future, Bitcoin will replace dollar, which will cause huge demand.

3. Conclusion

After analyzing the current situation and the words of industry experts, we can conclude that Bitcoin and cryptocurrency in particular have a great future. Now we are only at the beginning and in the next decade, cryptocurrency will change our life. It should be noted that this article is not a call for investing in cryptocurrency. These are just our subjective thoughts about the future development of the industry. Remember, any investment entails a certain risks.
