I have had colleagues who enjoyed casinos. On a business trip, they stayed out late on the Friday night, and it involved cards, drinks and losing money. It does nothing at all for me, but they seem to have had a good time.

I have had colleagues who were cryptocurrency enthusiasts.

The casino enthusiasts did not say "we're going to replace the international financial system with casinos! Poker chips are better than dollars!" No-one stumbled wide-eyed up of the casino at dawn, up $1K, insisting that this was the future of the economy for everyone. After I said that I wasn't interested in poker or roulette, none of them tried to preach the value of poker or roulette to me.

Because they knew it was a game. An adult game with real money at stake; but all the same, just for play. The cryptocurrency enthusiasts did not have that same level of awareness.
