At the Bitcoin, as a minimum, a rocky week. At the lowest point of this cryptocurrency estimated at nine thousand two hundred dollars, but after the uptrend could throw it as much as the mark of twelve thousand dollars. Bitcoin community has mixed feelings about Tether. On the one hand, the currency plays an important role in reducing prices. But if this line was cut off, then kriptovalyutnye markets would be hungry to new money. While Bitfinex, which controls Tether, is responsible for the release of these tokens with reference to the dollar, other exchanges are also dependent on them, including Kraken and Bittrex. What is happening with Tether, affects everyone. The number of new the Bitcoin, produced each day is estimated at eighteen million dollars. Miners must sell most of the coins produced to cover utility costs. This means that eighteen million dollars should come daily to the markets, to maintain the current prices. Given that over the past four days and four million dollars was released in Tether, and yet the price of BTC remained sluggish, it is alarming. If not for a flood of new cash, then this week's drop would have been even stronger.
