...I already trade on Kucoin as a non-verified user so Kucoin would be still the best choice compared to FTX due to the withdrawal limit and there are more coins and pairs that you can trade compared to FTX.
I have registration on both exchanges and use each exchange to perform individual tasks. Since I keep the FTX exchange coin in the staking, I have one free withdrawal per day to the ERC-20 network and I use it if necessary. Ku coin is used by me only to buy new coins.
