I have the same feeling towards the stock market. Sure, it can be well researched information on the stock in question, but it's all a bet your interpretation of that stock is right.
Maybe some of that is available now with crypto? Index funds? But with how heavily the bigger cryptocurrencies are price-correlated, I don't think you get good intra-asset diversification benefits.
Personally within my asset allocation, crypto is a tiny fraction of a percent.
Your approach reminded me of a joke:
Three statisticians go deer hunting with bows and arrows. They spot a big buck and take aim. One shoots and his arrow flies off three meters to the right. The second shoots and his arrow flies off three meters to the left. The third statistician jumps up and down, yelling "We got him! We got him!"
Most of this stuff is actually worse than casinos. Casinos have a social component, employ people, and are often at least a little regulated so that the odds can’t be absolutely 100% toward the house. Also you win actual money not a virtual game item.
