I do. Bunch of tokens in CMC are using this kind of method to attract investors to earn passive income from there by holding their tokens. I don't even wanna call this as use case. This is not related to the usability for the token but this is a passive ability for the token. The only problem is where such token get the passive income? in my opinion if majority of these tokens didn't have product and how is it possible to generate passive income to be distributed to the holders?

So what kind of altcoins? It's pretty similar like ponzi. Oh but that's ponzi scheme. This token will give you hourly payment by holding such asset. Don't join in this token. You may be scammed.
