Crypto currency is a special kind of banknotes, which is not issued by the national bank of any state, but by an electronic payment system. This technology appeared relatively recently - in the late 2000s, so many financial experts still distrust it, nevertheless, operations with crypto-currencies are capable of generating tangible revenue.
How did the first crypto currency come into being?
Once the world learned about the Internet and began to actively develop it, electronic money quickly began to appear, which were intended to replace the "real" ones. Several years ago, payment systems became a technological breakthrough, and today electronic transfers, wallets and cards have become a part of our life. However, here the financial revolution as such did not happen - at the heart of payment systems lay all the same traditional currencies. The beginning of fundamental changes in the world of money was the emergence of the crypto currency. In the distant 2008, a certain Satoshi Nakamoto laid out in open access the protocol developed by him for the interaction of computers in the network with blocking technologies. This was the moment of the birth of the first crypto currency - Bitcoin.
The first electronic purse with bitcoins was launched on January 9, 2009, however, it functioned only in the test mode. Almost the whole year, the elimination of errors and improvement of the functionality of the system continued, in particular, the service began to support the Linux OS and the API appeared, which made it possible for its use by third parties.
The first step towards the popularity of the crypto currency was the opening of the forum in November 2009, before that Bitcoin was known only to a narrow circle of people, most of whom were familiar to the creators of the service. The increase in the number of users revealed small vulnerabilities in the security system, however, they were quickly eliminated.
Full value currency bitcoin was only in May 2010 - it was then the first purchase was made. The buyer was the American Laszlo Henec, he traded 10 thousand bitcoins for two pizzas. Then this deal seemed successful, because it was possible to get something for the virtual currency, but if Laszlo did not buy pizza and saved the money on the account, now they could get about $ 7 million for them. The ability to exchange virtual monetary units for real ones the goods became the most important events for the crypto currency.

In the century of ubiquitous dissemination of information technologies, universal means of payment that could be calculated in electronic space without binding to a certain country or institution are in great demand.

And because of the absolute decentralization of the emission of virtual coins, they can neither be counterfeited nor prohibited.

Nobody can track your financial transactions. For this, cryptographic (mathematical) hash codes were invented. Each financial transaction is assigned its own hash code. It is unique, protected from forgery, and is not used again.
