Well, I can not deny the fact that this is a vital information you shared @op, but unfortunately, like some other users have said, I think I go inline with their opinion.
While reading the OP, it was the same thing I had in mind, the casinos listed on that table are not so popular, and as such, investing in their bank roll is highly risky, and another thing is that, we don't even know the people that run this casinos mentioned there, that could be another risk all together, I won't advice interested users not to invest but it's a no for me personally.
Bustabit and Bustadice arent that popular or known? Considering and in speaking with their reputation then i would say that i would recommend if you are really that making some investment on their bankroll.
Yes, we know that particular risk since we dont really know on who's the owner but rather into those known account names but on personal identity? There would really be no way on getting those funds
back if in case that there would be some sudden ran away with those funds which there's no way that you can possibly sue someone for that.
Among on the list then those two are the ones which i would be comfortable with if i do have the funds.
