This exchange is very similar to Binance and similar in functionality, but I think that Binance will remain the leading crypto exchange in the next 1-2 years. Binance does a lot for its users and most simply will not leave this exchange.
I agree with most of what you say, but its good to remember Bibox is only 1/17th of Binance marketcap, yet the daily volume is around 15-20%. BIX token works the same as BNB where as you get 50% off of the fees, but also in addition they
distribute 30% of all trading fees to BIX holders. Currently annual ROI is 20-25%. I dont doubt Binance will do well in the future but Im pretty sure Bibox will also, as we can see it regularly be in the top10 exchanges by volume.
