I am not a regular user of the Poloniex exchange, I prefer others, but it also undoubtedly has advantages. At one time I got acquainted with the Poloniex exchange based on reviews on the website Revieweek.com (https://revieweek.com/review/poloniex/) when I was looking for a suitable platform. There is a stacking, an over-the-counter trading platform and an internal payment system, but I didn't like the fact that there are almost no updates on the exchange, everything is old or something, almost everyone has it. Now I use the exchange on a case-by-case basis, but for beginners I can still recommend Poloniex as a good choice.
