Any adult entertainment coins were bad coins. 99% of coins that used adult entertainment as their idea became dead project. There's no need to mention some but you will fine lots of dead project related to the adult entertainment in another section (announcement & token altcoin).
It has no real use case, mostly to be a payment system for adult entertainment but that's only a plan.

I don't even call that as a promising project but it seems like that you have different opinion about that. I respect it.
It's only wasting your time and your money. Investing in crypto adult coins will give you nothing. It's totally non sense investment for now.
