The principle is usually the same too with all tokens (including stable coins). The creators of such tokens have no money, no revolutionary idea or anything they could use to make money. So instead they sell "air". They simply create these tokens and start selling them to newbies, making money in the process!
The fact that there is also "staking" on top of it where you get profit for holding your bitcoins in THEIR pocket shows what a filthy Ponzi scheme this is
These things don't fall apart like regular schemes since there is a market where people keep trading them. In other words some of them manage to create an artificial utility that lasts as long as the gamblers keep trading. Then it falls apart catastrophically.
