Just discovered that guy from the Air Cloud Union, when Circle was about to open, deleted the tweet planning to short Circle. Actually, it wouldn't have mattered if he didn't delete it; before and during the trading session, the stock price made a dramatic move.
Additionally, today before the market opened, when Circle touched 237, the shorting fee rate reached 9%.
It's not crowded on the long side now; everyone is looking for opportunities to short..
