So what happened today?
We saw a big leverage flush.
Anyone who longed near the top with a leverage of 10 or higher got liquidated. Open interest (the entirety of long+short positions) decreased substantially. It was the biggest liquidation event in 2 months, and either shows what's to come or marks the bottom of this move.
I'm betting on the latter. Strong alts should continue to perform well, as long as $BTC holds its range. Identifying these altcoins is a tough challenge. $TOMO and $SXP held up pretty well during the drop. $ICX is recovering strongly. $LTC and $ONE showed strong performance before and are both resting on their respective support.
