I like this exchange. Bitstamp is an official and registered in the European Union Stock Exchange. The main trading pair (even one can only say) is BTCUSD. Of the pluses - she never noticed such problems with insider trading as kraken \ poloniex and тп, where in the midst of trading there is a lot of lags, after which a candle pays out the whole glass, and the management of the exchange then writes that we were attacked by hackers and we are not in cases So, I did not watch the bitstamp of such problems.
