The future of gambling is always uncertain. Like gambling, you invested a few dollars, and if you can win you will get double. But there is uncertainty with it. And there is no need to practice gambling. Only you will be able to invest in risks. As a result, you can win.
So, in my opinion, the best practice of gambling is to invest more.

You must stop thinking that whenever you deposit bitcoin to a casino it's already an investment.
That's already a wrong mindset and you shouldn't practice that when you gamble. You may don't have to practice gambling but you should start practicing some other practice on your own when you gamble.
