Tonight, August 22, bitcoin in minutes up to $6816, rising more than $350.
This event coincided with the beginning of engineering works on cryptocurrency exchange BitMEX that alerted users. BitMEX is very popular and offers the opportunity to the downside for rates.
A few hours later the representatives of the exchange said on completion of the work, and also reported about a large DDos attack. Because of it a significant portion of users are unable to login to their accounts.
At the moment bitcoin corrected to $6686. The rest of the market behaved similarly: altcoins after bitcoin soared, and then slightly adjusted.
The growth of bitcoin has led to the fact that the total capitalization rose to $222 billion, and then fell to $217 billion several weeks ago, the figure was $190 billion.
