For me, Poloniex functions just like any forex broker. Other cryptocurrency exchanges do not have the same level of functionality and trading opportunities as Poloniex. I encountered similar tools a couple of years ago when I worked in the forex market: there, brokers provide all the necessary conditions for trading, the charts are serious and customizable, allowing you to adapt them to your needs. This exchange almost completely follows all the trends of forex. The only downside of the platform is the lack of the ability to conduct financial transactions with real currency. To fund your account, you need to use bitcoins or other forks, which requires purchasing them from exchanges. Thus, during periods of high cryptocurrency volatility, I often lose income simply because I can't deposit funds into the exchange in time. Overall, Poloniex is one of the best exchanges for working with cryptocurrency at the moment. However, it is not perfect; if basic wallets, including foreign ones (personally, I would be satisfied with WebMoney), were available, this platform would have no competitors.
