A good exchange and trading instruments are good. Poloniex is certainly not for beginners. You need to already have cryptocurrency to start trading on Poloniex. However Poloniex is a industry leader in altcoin trading, many coins not available on major exchanges can be traded on Poloniex. Poloniex very often is DDOS’ed during peak trading hours, and customer support is not very responsive.Посмотреть отзыв полностью
