He might say crypto is one of those digital assets that can give us profit in the future and when we bet using crypto (bitcoin) in sports betting and win, it is considered by Op as increasing investment return.
Even though what you need to know (OP) is that not all gamblers provide benefits, except for professional gamblers with all the analysis who have a high chance of winning at sports betting.
Another thing that must be known is that gambling is a place to throw money with an amount that can afford to lose but the gambler gets pleasure.
So increasing profits at gambling on sports betting, it is not the right choice.
Especially considering that crypto prices fluctuate very much when you lose at gambling and there are a number of assets left but the price drops, that doesn't increase profits.
