I've been hearing a lot about Poloniex as a
cryptocurrency exchange, but I'm still not sure if it's a good fit for me. Could you please shed some light on the key factors I should consider? Specifically, I'm interested in its security measures, trading fees, coin selection, and customer support. How does Poloniex compare to other top exchanges out there? I'd also like to know if there are any common issues or complaints that users have faced with Poloniex. Overall, is Poloniex a reliable and trustworthy platform for trading cryptocurrencies?
