At least OP choose the lesser evil between the two
I have not tried myself investing crypto games. Well, better than gambling all your money and lose it all, this is a smart move on your part. Investing on the house is sure to have a greater chance of earning or profiting from every game they hold.
Yes, it is good thinking to invest money on casino bankroll than gambling but to reduce our loss, it is good to diversify our money and put in few real casinos instead of just one or two. If any one guy wins big amount, then you will lose a lot of money and need to wait for long time to recover those losses.
