Are you talking about those new coins running on BSC network? Because BNB isn't like those projects, BNB will rule in the future but most of those new coins are garbages and in bear market their true motives will be revealed, all I can say is even shitcoins have good opportunity to make anyone rich right now so don't hesitate to take your own chance from this opportunities
Yes mostly are BSC network created, I am new I don't actually how it works, I think they could get fees or something for enabling this feature.
I am too late into this bitcoin thing, therefore I want to step in, however looks crazy. They create coins with the number of quadrillion

Bitcoin has just about 18 million at the moment. But I was wrong about BitCoin in 2010, so I could be wrong again
