You have really taken time to explain what centralized exchange is and list the 5 tops centralized exchange. Your choice of centralized exchange is my choice too. Alot of people complain of thier binance account verification taking too long and so you so. Mine is the opposite, I took me just 10 minutes for my account to be verified. In fact when I got the verification email, I didn't believe it. I had to confirm and check over and over again. Expecting maybe another or final verification will be sent to me. I didn't have issue at all. You have written so well, I wish you success in your entry.
