Degenerates on Binance with up to 150x leverage (borrowing Tethers to buy crypto) have been building up their margin account balances to big numbers, and when they make money, they double down, and build even bigger positions. Because they're degenerates. But when the price dips below a certain point, some degenerates who have these margin accounts are suddenly below their maintenance limits, and they get liquidated. When they get liquidated, Binance will sell your crypto for Tether, and you are left with little to nothing. So what happened? Crypto got sold, and Tether got bought. Because Crypto got sold, the price drops, which triggers more accounts, who thought they were safe, to dip below their margin maintenance requirements. This creates a feedback cycle which basically ends in the liquidation of all the margin accounts. It all ends in a very fast, cascading crash like we just saw. The bad news is the price is lower, but there's a silver lining. The good news is the market is in a healthier position after this. Most of the unsustainable degenerate margin accounts are probably gone. If we go up to $60k in the next week, it's not because of borrowing (as much). Going forward, at least for the near term, another event like this is not very likely.
