I think this is the last time that such kind of price movement happens due to ASIC manufacturer dumping pre-order bitcoin

Currently there is a huge demand for ASIC devices, therefore many previous bitcoin owners re-investing their bitcoin for ASIC devices, but ASIC chip manufacturer still do not accept bitcoin, so all these coins must be sold on exchange for dollar

But soon they will find out that ASIC devices are everywhere, these bitcoin investment will almost never ROI after skyrocketed difficulty, then in future they will not risk that much of bitcoin anymore

ASIC is the last step in hardware developement, from ASIC forward, there will never be a 40x increase in efficiency, any kind of future upgrading is more gradual
