Mark Cuban Calls for Defi Regulation After Crypto Investment Goes to zero. Last night, billionaire investor Mark Cuban said he was “hit” by the sudden collapse of a cryptocurrency called TITAN; the token shed nearly 100% of its value over the course of a few hours.
Now, after losing what he’s characterized as a “small” percentage of his portfolio, he’s calling for increased regulation around stablecoins - a subgroup of cryptocurrencies meant to hold a “stable” value tied to a particular fiat currency.
