The cost of one bitcoin is approaching $ 3,000. The Bank of Russia is working to create a national virtual currency. AMD and NVIDIA are preparing to release graphics cards optimized for mining. If you still have no idea what a cryptocurrency is and why there is such a fuss around it, the Lifehacker cards and the BestChange exchange office monitoring service will help you figure it out.

 

What is called cryptocurrency and why is it needed?

Cryptocurrency is a so-called artificially derived currency using digital technologies, which has reliable electronic protection thanks to cryptographic technologies. These monetary units have no physical counterpart, they cannot be traded or understood, they exist only in the virtual world.

The name for digital money - "cryptocurrency" came into use after the publication of an article about bitcoin - the very first and most popular digital currency and payment system around the world. Bitcoin originated from Satoshi Nakamoto, but who hides behind such a famous name is still unknown to anyone. Nakamoto introduced the concept of a decentralized payment system in the fall of 2008. Its main principles are: anonymity for all participants, protection against fraud and independence from regulatory organizations, and much more.

Bitcoin is made up of interconnected blocks of various transactions. Each subsequent block of this chain contains information about the previous one, so that you can build them into a single link and get information about all previous transactions (works like a system DNA). The process of creating new blocks is called mining. For the next block to appear on the network, you need to generate a cryptographic signature and a code for it, for which you can get new bitcoins. By the way, throwing them out is not an endless process, everything has its end, for bitcoin it ends in 21 million.

It was relatively easy to create blocks at first, and lone miners did it too. Over time, the complexity grew, mining required solid computing power, so miners began to unite in pools and mine new bitcoins with joint efforts.

 

Cool. Can it be simpler?

To simplify everything, the Bitcoin phenomenon can be explained using the example of lemonade caps (yes, hello to Fallout fans). Let's say you can't fake these caps, go shopping and buy all the lemonade too: it is no longer produced. The number of lids is limited and is known in advance, so you just have to wander and look at your feet - suddenly you come across a lid.

 

Like any limited resource, caps have a certain value that grows as demand increases. The first covers are easy to find, but the further you go, the harder it gets. People have to unite in groups and spend a fair amount of time and effort to find the next cap. They exchange the production for all sorts of necessary things, and many even make stocks of caps in the hope that over time their rate will only become higher.

 

Why do you need such a currency?

Then, what is the use of ordinary money: it is a universal commodity, which is a measure of value when buying and selling other goods.

 

There are several significant advantages to cryptocurrency. First, it is not afraid of inflation. If the printing press goes crazy and stamps a crazy amount of rubles, it is logical that this money will be worthless. With bitcoins, such a situation is excluded: remember that their number is known in advance and is limited.

 

Another plus is decentralization. There is no single center from which the system is controlled, which means that it is extremely difficult to disrupt the operation of this system by forcibly limiting the distribution of currency. The network simply does not have a single owner, it is controlled by users around the world.

 

The next advantage is anonymity. It is possible to track transactions and see how many bitcoins have moved from one wallet to another, but it is not easy to determine who exactly owns the wallet. Anyone can open a bitcoin account, for this you need the appropriate software and access to the Internet.

 

Since it's money, you can buy something with it. Or not?

Of course, you can. It seems strange that money, which, in fact, does not exist (in any case, we cannot hold it in our hands), has purchasing power, but the fact remains: it can be exchanged for goods and services in the same way as bills or coins that are in your wallet. Bitcoins can even be exchanged for other money - euros or dollars - at your discretion. In many countries, people buy air tickets and gadgets with bitcoins, use them to pay for utilities or a drink in a pub, even Microsoft accepts bitcoins.

 

Funny story: in 2013, a user of a bitcoin forum offered to exchange his 10,000 bitcoins for a couple of pizzas. Then the deal was quite profitable, but what this lover of Italian cuisine thinks about such an exchange now, we can only guess.

In Russia, due to problems with determining the legal status of cryptocurrencies, the exchange of bitcoins for goods or services is more complicated, so first of all, it is worth considering bitcoins as an investment option. At the moment, the game is definitely worth the candle: the bitcoin rate is growing steadily. The most profitable investments are associated with the highest level of risk, so choose what is more important to you: the opportunity to make good money or complete peace of mind.

 

How to start a Bitcoin wallet?

Go to the official website of the payment system and choose the option that suits you from the list of applications for Android, iOS, Windows, macOS and Linux. The only problem is that such applications can take up too much space, but in this case, there is another way.

 

You can trust a third-party Bitcoin wallet service like Blockchain. The registration process takes a matter of minutes: you just need to enter your email address and come up with a fairly strong password. In the "Security Center" section, you can link the wallet to a phone number and activate two-step verification in order to further secure the funds stored on the account.
