Binance is the number one crypto exchange now. And the projects are launched on Binance does not need an advertisement. Binance is more than advertisement for projects. I can say positive things for BNB but I find it risky to hodl.
Everything have some risk, it's up to the person how to handle and take it, binance already gaining lots of supports and success, with the launchpad
IEO projects really brings the BNB coins to a much better value, holders needs to be responsible in order to take the advantage and enjoy the profits.
BNB got so much of demand due to its 25% discount on the fee while using that exchange so it will give some profits for the traders but it is not a coin to hold so we never have to trust any projects simply because it is advertised by Binance.
