Hello Friends, 
TWTbep2 to TWTbep20 convert easy or difficult.
My personal opinion that it is difficult.
Idea for Trust Wallet team; 
It can be so easy if they do it like BNBbep2 to BNBbep20. If TWT listed in the binance then simply we can deposit as bep2 and again we will do withdraw as bep20.
What do you think?
Thanking you
