The Huobi exchanger is not bad but it can never be compared to BNB because BNB is still far ahead with which it is foolish to compare anything. The BNB has now become a very used coin and It's blockchain also a popular chain. so it is impossible to compare it with others
Yes as Binance exchange has a lot of updates and offering that users/traders enjoys like me , in my country Binance offers a p2p feature that made us transact with a very cheap fee in which now most of us enjoying ..
so i think Huobi will never take even that close against binance though Huobi is also a trustworthy exchange and there are many users of course though not that many as how much binance has.
