Unfortunately, these list are already operating more than 2 years ago before this listing, and investing these sites are not that profitable anymore that year or even now. Although i dont know if some of them are still operating their investment scheme.
We know because there eere also dates posted in the OP but how can you say that investing on these sites are not profitable anymore? Have you tried investing on them before? Although there are threads about it that I read last time and some feedbacks there are not that positive but I think it should work the other way, I mean crypto casinos now are more known than compared to before. Their sales must be high now so those who invest on them are also going to be profitable.
Honestly, I would have given all my money to get this information two years ago.
Why? If you give all your money then you won't have anything left to invest. Also, information like this are not hard to find but you can do it yourself. You can just search "crypto casinos with bankroll investment on them" in google and it will show you a huge list but you should first check their reputation or reviews to see if they are legit or not before you get started.
