Not recommended for people who are in rush since for sure it will take 24 hours or more before you can receive the amount you transact and what worse is sometimes you feel stress and seek for accelerators which you believe to help your transaction to fasten up. Better to use always what network recommends since this is more the safest and fastest way for us to have smooth transaction on timely manner.
I always choose the slow withdrawal as I don't mind if it arrives in 2h or 24h. But since they introduced the BSC chain to withdraw BTC and ETH, I always use this. Fees are a lot lower and the transactions go a lot faster, so it is a win/win!
I also always use slow withdrawal when I move BTC! I don't mind waiting... if I wish faster I simply go with BSC! Tron was the great alternative... but when the BSC chain appeared it was even better! I always point out how "fast and cheap" is important for people who really like to gamble (of course, not only for that...) and move funds from casinos to wallets, or between casinos! I decided to not use Ethereum, and all ETH tokens, ever again because of the high fees from the last years...
