It is better to diversify investment money in various casinos rather than investing all in one casino. This logic can be applied to every investment you make. In this case all you need to find 5 different casinos and invest $20 in each (if you got $100).
I still wouldn't be bothered though. Buying alts and hodling is much more rewarding.
It's very reasonable, dont put egg in one basket, doesn't just apply to investments in the crypto world, I very much agree with you.
