Yes, it would blow my mind.
Markets (especially crypto) are not that efficient.
They don't need to be. You don't need to (and I don't) fully accept the Efficient Market Hypothesis to believe that a known event will be reflected in the price in advance.
Markets become efficient when user profiles increase. Now compared to other forms of market hypes bitcoin has its circulation keep on increasing which is good for a stable growth.
We all waited a long time until the value will be more and that is perfect for us.
The people who sold short when the price was $450 will not be so happy. No more than 50% of the trader will be happy.
For the bitcoin trading, it is better to buy the bitcoin for the long term. Sell short only when there is a big bubble.
