Poloniex is one of the first floors I join in the market, low transaction fees and fast speed friendly interface.
 Gradually they started to have problems such as margin lagging floor margin of all kinds of user tricks that do not protect users like binance do.

I mistakenly transferred my usdt wallet into my wallet, but they didn't help me to regain their poor customer care ability.
They will not change and the number of users will become less and less.
Hopefully they will change their policies and operations
