Altcoins mostly get so influenced by the bull season of Bitcoin that some of the altcoins get pumped, and after they dump, there is likely a 0.1% possibility of the token rising again.
Generalizing the altcoins market as shitcoins is wrong, though we might have different views, your presumption that there's only a 0.1% possibility of the token rising again, which is close to impossible, is baseless. Have you gone through checking the altcoins market? The first altcoin that enjoyed enormous success was Ethereum. Back then, BNB was just a token for Ethereum before they had their own network, and guess what's one of the biggest exchanges now? Isn't it Binance?
The point is, if it does not start as a Eth Token, Binance woudn't be successfu and the present time and you are probably benefiting on the existence of the exchange since most traders favorite is Binance.
Look at the history of BNB and see how profitable it is.
The price of Binance Coin during the token sale was $ 0.15 per BNB. The Binance Coin token sale started on Jun 26, 2017, and lasted until Jul 3, 2017. Compared to its initial token sale price, BNB is currently showing an ROI of 1,435.52x against the US dollar, 132.63x against Bitcoin, and 248.52x against Ethereum.
