Well, no, some stocks actually have value, because there's a money-making company behind the stock. (Or are you using "stonk" to refer to a stock that has a money-losing company behind it?)
Bitcoin's project is that it's a collectible with limited supply.
Buying crypto because you believe in a given project is the same as buying a beanie baby because you happen to like the particular appearance of said beanie baby.
I wonder why that is...
