BNB itself is beneficial and I think you should hold it. BNB is a successful token and from many others coins it is better to hold but still if you want to exchange it with other successful project then I will suggest to invest in bitcoin. May be you want to exchange BNB with any other coins because altcoins are not trustworthy and they have no guarantee to have a successful coin, but i think it will provide you more profit and if we talk about a another project so we can say that there is no other project which is trustworthy because crypto is itself volatile then how its project can be trustworthy. I will suggest that keep holding and if you want to exchange it then surely select bitcoin as the chances of losses are not as high as that of altcoins.
