A possible explanation for the events that occurred last night in crypto land.
tldr: margin accounts having a cascading crash on @Binance.
1/ Traders on @Binance with up to 150x leverage (borrowing Tethers to buy crypto) have been building up their margin account balances, and when they make money, they double down, and build even bigger positions.
2/ But when the price dips below a certain point, some traders 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.
