There will not be any problems if you participate in trading at Bitfinex because this exchange has very good liquidity for investors and the withdrawal is very fast so this exchange is still A good choice. I use it mainly to trade alts. Last time I used it was a few days ago. I could not pass the x3 stake reward at eth20staking.org and their transferred 100 ETH to my wallet pretty fast. I won't comment on the verification process because I have an old account with them.
