Guys, I suggest you to add BNB token for margin once you launched platform. This coin is trendy and you will increase volume by doing this action.
I do not think that it will be correct to develop another exchange. If you want to sell tokens for this token, you need to go through the listing on the binance.
I see nothing wrong with that. It will be a very correct decision together with exchange native token add such tokens as BNB and HT. It is already implemented in many sites .
