I'm curious about this too, but only the ones that have the best RTP for investors. Remember how predatory BetKing was?
Just-Dice was the best, then YoloDice like you mentioned. Bustabit seems to take 60% of the profit as commission which is also predatory (you take all the risk and they take 60% of the profit?). Worse than government taxation.

But great question OP, definitely monitoring this thread.
Just-Dice still accepts investors but the site has moved to CLAM gambling instead or DOGE like it used to be. I stop in from time to time and still see people using the site, I think investors get a % based on their investment every few minutes.
