Definitely it's going to be CZ (Chanpeng Zhao) of Binance. This is because I'm extremely impressed with his development progress so far. Binance has evolved from just an ordinary exchange to the best. So many innovations like BNB moving to its own blockchain (Binance chain), Binance info for good verified  crypto updates, additions to the exchange like margin trading and lending and also the launch of Binance DEX. These are just a few points coupled with the fact that, he is my mentor. I do like the way he handles issues too, in order  to  overcome FUD example ; rumor of KYC document leak.
