Rates of major crypto-currencies have fallen sharply

During the day, Bitcoin has lost more than 6%.

Over the past day rates of major cryptocurrencies, including Ethereum, Ethereum Classic, zcash for, Monero, Siacoin, fell by more than a quarter. “Ether”, which cost early in the week, $ 240, on the morning of 11 June, you can buy 170-175 dollars. Because of this marked increase in the number of proposals for the sale of video cards and mining-farms.

Peak rates of cryptocurrencies was in the middle of June, when Ethereum has risen to $ 400. Experts talked about speculative growth and the danger that soon the bubble will burst, however, the situation attracted the interest of the inhabitants to mining — “mining” cryptocurrency, using the computing power of graphics cards. Anyone can install on an ordinary PC running Windows or Linux one of the programs for mining and actually maintain the operation of the system of one of the cryptocurrencies. For this system, “voznagragd” it, giving “coins” relevant currency. Centre issue no, the reward is inherent in the algorithms of cryptogenes. The more the total capacity of the graphics card, the more reward per unit time.

This has led to a shortage and a strong increase in the price of graphics cards. For example, the Board on chip AMD RX 580, which is immediately after the release in April cost about 15 thousand rubles, in June it was sold for 42 thousand. The payback period of this video was very varied as it depends on several variables. On the one hand, the growth rate of the cryptocurrency in relation to the “real” money like the dollar, increased the profitability of the graphics card. On the other hand, cryptocurrency is designed so that the more miners their services, the less the award goes to each of them.

At the peak of the “Ether” one video card on the AMD RX 580 with 8 GB of memory brought to 7 dollars a day, while electricity costs were (and are) about 20 cents a day. The ability to quickly and easily earn attracted many comers “of the people”, whereas before mining was engaged enthusiasts and those who are able to invest in the company millions.

Now the same charge mainit “Ether” less than $ 2 a day. If the course is not to grow again when the current total power of Ethereum, each video card will pay off at least a year. On “Avito” and other sites, a lot of ads about selling graphics cards and mining-farms (computers with multiple graphics cards), and money for the device asking for one and a half times less than in June.

The Bitcoin exchange rate has declined by about 10%. When “mining” the cryptocurrency used computing power but don’t need fast memory. Therefore, for Bitcoin mining some years ago has developed specialized processors (ASIC), which is much more effective graphics cards. As a result, today, bitcoin mining using GPU is economically inexpedient — the rewards are not worth the electricity costs. “Mining” Bitcoin has become a business for large players with their mining-farm, mainly in China, in the regions with cheap electricity.
