That's what many investors don't understand and I would also add that crypto brings out the crazy in many of them, very much like the great bull markets in stocks.  Either they run up their credit cards to buy more or they buy on margin, which is the same thing as taking out a loan.  I  have read stories here about credulous investors mortgaging their houses to get money to buy bitcoin.  That is insanity to me.

This gentleman in the UAE might have risked money he could pay back but what he did was incredibly risky and stupid.  Nobody should be taking out loans to buy something as volatile as bitcoin.
