poloniex is the first exchange that I use when I know cryptocurrency, in my opinion this exchange is very easy to use, customer support is quick to respond to my problems when I have problems when using their platform, so the problem can be resolved quickly and it really helped me, the KYC verification process even very quickly only takes 24 hours the verification process is complete and the account can withdrawl smoothly, but Poloniex does not have a deposit feature using a credit card so users have difficulty making a deposit directly through the Poloniex exchange
