This distinction is so tiring. It's just not interesting calling something gambling as if that is supposed to be bad. Every move we make is a gamble (yes, even storing that precious cash in the bank). Money is all about opportunity cost and choosing to do nothing is just as much of a gamble as doing something like storing it in bitcoin. Sticking ones head in the sand doesn't change the fact that your only choice is to place your bets and gamble.
Bitcoin is also not zero sum, it's a monetary system with unique properties (particularly censorship resistance and resistance to seizure) that can't be found in any other monetary system.
Those qualities add value in a way that makes it attractive to buyers even if they expect the price to go down over time.
I think you are the one with your head firmly shoved in the sand. Bitcoin has enormous problems with legality, energy usage, lack of trust, hacking, and slow, expensive transactions that make it a really shitty alternative to fiat. Bitcoin isn't just a gamble - its sole use as of now is as a pump and dump scam. There is no earthly reason why a digital token should be worth $50k a pop. Bitcoin is a shitty bet, and I'd take USD and a bank account any day over it.
