$JCT -hour drop of 15.4%, to 0.006142, with a 24h range of 0.004921 ~ 0.008491.
I’ll use the range before the move as the dividing line: it only counts as a breakout if the price holds beyond it.
Sharp drops often come with mass liquidations of leveraged long positions, and sometimes a short-term rebound follows once the washout is over.
