But ok, gamble away your money for worthless crap if you believe it's the same as owning non-distributing value stock (lol).
I can point to any number of companies whose stock has proven to be worthless crap. It is the same type of gamble for both. Neither have any value arising from business operation. The value of a cryptocoin and the value of a zero-dividend share arise solely and entirely from investor faith.
Money is real in exactly the same way that zero-dividend shares are real, or that cryptocurrency is real.
The difference is that the government can freely adjust the value of money, and anyone can create shares. Cryptocurrency can only be generated per the conditions of an algorithm.
