it all depends on how the developer is planning in the future. BNB has been successful with the scheme planned to date. their market remains strong and as long as their exchanges are still fine then I think BNB will remain safe. and for other exchange coins not just HT, all have the same opportunity. moments can be created, depending on how the team plans and functions their coins in the future.
Their opportunities are the same but their progress and improvement every year Binance always gives their best where their development is quite fast and now maybe more and more users in binance.
HT and BNB cannot be differentiated because both have their own performance so the opportunities will be the same if they do good development.
