Many say that the market was due for a drop and I agree, my only observation is that the tweet and the drop correlate in time and thus initiated, and probably accelerated the drop.
While many seem to have understood that the main purpose of this publication was to accuse Elon Musk of manipulating the market and whether he caused the drop or not, the real question was actually why he/Tesla went "all in" on BTC to then change their mind about accepting BTC for their cars.
That debate is still open ...
