Bitcoin led a pullback, with all major term IVs still rising

Bitcoin led a pullback, with all major term IVs still rising.
Tomorrow is the annual delivery date, which is generally not too volatile, while around the delivery date there is generally a decline in medium term IVs.
As we can see from the block trading data, call option shifts dominated the absolute block of today's trading and market makers will tend to close some positions early before expiration.
Annual delivery is likely to remain on a smooth finish with IV likely to see a few percentage points of decline.
