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.
Diversifying has both upside and downside as well. Now if you ask me would I rather give 20+ casinos all my money and then wait for them to profit or just one good place like crypto games then I would opt for just cryptogames because in 20+ casinos some of them are bound to he shady. However, if you tell me just couple of casinos that I really trust then it could be another case.
Diversifying for just sake of diversifying would be horrible, putting your money in multiple income sources is always a great idea in case one gets stuck for a while but also putting your money into stuff you don't know or not trust very much is a risk bigger than the one place investment. I would rather divide it into 3 places that we all know and just hope that it gets a good return for me but I wouldn't put it on 10+ places I never heard of.
This is the same with cryptocurrencies in general
People had been "diversifying" by pouring their hard-earned cash into all kinds of fraudulent schemes (like shitcoins, shittokens, rogue casinos, and whatnot). And when everything started to crash at the end of the day, they were bitterly surprised by the results of their "diversification"
It turns out that when you diversify recklessly and thoughtlessly, for example, by investing in every new casino on the block, you are not so much increasing the odds of making more money as essentially multiplying your chances for losing most of your investments
Diversifying your investment is just part of the strategy to minimize the risk, it is necessary that you choose the right project based on your opinion and this one should be a well research project whatever it is. In gambling, it's easy to find a good and reputable gambling site but there's always a risk since you are putting your money without insurance, unlike depositing in banks where you can recover your money in case of bankruptcy.
These are just part of the risk, we make our own decision, hence we should access of its result, if we are good and lucky, most probably we will end up profitable in any venture we will make here.
