Poloniex is a crypto exchange based in the United States, which offers maximum security and advanced trading features. In 2015, the exchange had a grand redesign, where they added a wealth of different features to improve their service and to provide a fully immersive trading experience. They have unique technical analysis charts, allowing their customers to stay abreast of news flow and analyse any price trends before taking a position. They also offer a live chat function, should their customers have any problems. Poloniex prides itself on being a very secure exchange, and they keep most of their customer deposits in an offline air-gapped cold storage, and have dedicated auditing programmes, which are designed to monitor all exchanges and report and block any suspicious activity. They also have a good volume and orderbook depth for the majority of its trading pairs. They have flat trading fees at 0.25%, and all deposit and withdrawal fees are subject to the blockchain’s specific minimum transaction fee.
