Bitcoin uniquely exhibits positive drift AND positive spot-vol beta, meaning it crashes upwards. Call options are the simplest way to take advantage of this positive spot-vol relationship, allowing you to be long delta and vol (vega and even volga partials).
Gap up 50 points and immediately dump during market hours. 6795 was definitely a magnet that has now rolled off allowing a bounce and potentially a continuation higher. Very likely the customer closed these calls once ES filled its weekend gap up.
This wasnโt โmms unloadingโ or unwinding their businesses or whatever. Go back to being retarded and study OPEX in a negative gamma and charm environment after a large vol move
Or find a quant to do it for you ;)
