I don't have account on Poloniex and can't check that by myelf, but Pmalek should be right.
See
the post made by Oshosondy on another thread some days ago.
You can create an account on Polonix without KYC. Just email and password is required. If you do that, you will find it to be true. I took that screenshots the time I was posting. It is very true.
i have account there, fees to withdraw btc is this, but, i use other low fee s coins...
You are using altcoins and not bitcoin. Use exchanges with low fee. Onchain withdrawal fee on MEXC is $1.8. After OKX was banned in my country, I started to know that MEXC has been an exchange I ought to have been using few years ago but I did not know I was missing something. It has the lowest trading fee also. You can also withdraw up to 10 BTC worth of crypto daily on MEXC without KYC.
