Personally, I'm looking forward to telling my landlord that I can only pay half my rent because I lost the money I'd set aside for it in the crypto markets.
Renter loses half their security deposit after landlord puts it into Bitcoin
A Reddit poster asking for legal advice reported that when they moved out of their apartment, they received only $1600 of the $3000 they provided to their landlord as an initial security deposit. When they asked what happened to the rest of the money, the landlord explained that they had put the money into a "money market account" that had lost value, then admitted they'd invested it into Bitcoin. The landlord tried to claim that "this is how a lot of landlords operate now", despite most likely falling afoul of guidelines on how landlords are supposed to hold deposits.
