Criptocurrencies are no longer a joke from the life of a sysadmin

Now the blockchain is used mainly for crypto-currency transfers, but it is increasingly being introduced into various organizations and for different purposes. And what is better with Blockchain? So, if you sent a cryptocurrency or information on the blockchain, the evidence of such sending can not be changed or faked, as it is confirmed by hundreds of thousands of computers around the world. The same computers store a lot of copies of this information - and it is available for viewing to any user at any time. The whole process of transfer takes a few minutes and costs ten times cheaper than banking. If you keep money and information in the blockchain, the records will never be lost or tampered with, any market participant can make sure of your financial solvency at any time. No third parties and intermediaries, only full transparency and mathematical guarantee of accuracy of calculations. More about crypto-currencies. Why do they need to be mined? Mine the crypto currencies means to confirm the transactions in the blockchain and receive for this a reward from the system and the parties of the transaction. To do this, you will need powerful computing equipment. For bitcoins special chips are used, for other crypto currency - video cards. That's why you can not buy for yourself or your child a new video game card - all cards are bought out by miners before they are delivered to the store. How can you start to mine? Entering this market now, you will compete with industrial miners, who have the newest and optimally tuned equipment and the cheapest tariff for electricity. With a good ratio of the rate and the number of miners in the system, you will be able to make a profit within a few months - and, most likely, will return the cost of equipment. However, with a temporary drop in the course, you will have to be patient. You can, of course, switch to another currency, which is temporarily more profitable for mining, but such anomalies are quickly discovered by the market, and the rest of the poor fellows come along with you. So this is a difficult way to earn money. Maybe it will seem that this entire history with crypto-currencies strongly resembles a financial pyramid, but it is not so.
The main goal of the financial pyramid is to enrich its creators by investing from new participants. The assets of such pyramids are not needed by anyone on the external market, they do not have any advantages in use, they do not solve any problems. In the case of crypto-currencies, on the contrary, they solve a big problem of the financial market, their turnover is convenient and beneficial to its participants, which creates a real demand for their purchase.

The main reason for the growth of bitcoin and other crypto-currencies is the entry of large players into the market, which no longer regards bitcoin as an anecdote from the life of a sysadmin, it is a financial asset, volatile, complex, but quite real.
