Regarding the fees I was asking if there were any hidden fees or bad exchange rate, but I remembered that a few weeks ago the service was hacked so I am now looking for new alternatives.
You can use Mexc, BitMart or Coinex.
BitMaxz posted about Coinex here on the other forum:
https://bitcointalk.org/index.php?topic=5512011.msg64602133#msg64602133. I have not used it before.
I know about Mexc and BitMart.
Registration on Mexc is just your email and password. Nothing more than that. Daily withdrawal limit is 10 BTC
After registration on BitMart, you will be required to input your country of residence, your name and date of birth. Nothing more than that. Daily withdrawal limit of 0.5 BTC.
Mexc is recommended. Lower trading fee and lower withdrawal fee. No other information than email and password.
Trading fee on BitMart:

I have withdrawn coins on both exchanges several times before.
BitMart support lightning network.
