What's wrong with BNB itself? That's one of the best altcoins out there, is rather hold my BNB or trade one for BTC, BNB is a diamond on its own, you can keep it and find another means to buy BTC.
There is no doubt that bnb is a top cryptocurrency and token of a major exchange like binance.But you should always be careful in buying tokens of exchanges and never invest all of your capital in tokens of exchanges.Exchanges can be subject to any risk at any time.Because an exchange's token is limited to the exchange itself, if the exchange crashes, its token will also crash.FTX Exchange Token was also a very powerful and popular token but after FTX Exchange crashed FTT Token fell to the ground.And secondly, never invest all your capital in one cryptocurrency.Rather, everone should always invest their capital in different cryptocurrencies.So that even if a one cryptocurrency project fails, your entire capital is not lost.
