That's a huge amount of money. If you only invest in bitcoin, you can make huge profits when the bull market comes. That was a mistake and you have learned from that lesson so you have at least some experience with tokens in casinos. Maybe if you want to invest in casino tokens, you shouldn't take too much risk based on your experience because we don't know what will happen with the tokens. It's better if we invest in bitcoin which can clearly provide big profits in the future.
The comparison of investing in casino tokens or putting money on a gambling site's bankroll with investing in bitcoin seems not appropriate. I'm sure everyone knows that putting money in Bitcoin is a must. That user was able to spend $25,000 which makes me think he did some DYOR before taking the risks.
There's no mistake in putting money on gambling sites on their investment side. The mistake was, that the user didn't manage properly the investment on the way leading to that loss. Although he can't control the flow of the gambling site obviously, considering an exit is a wise way to minimize the possible losses and then move forward on other investments later on.
We can suggest him invest elsewhere so he can get more profit. And he should also be able to know when to get out of his investment with a profit and don't continue investing if he can't see a profit.
