The mentality of a small position is completely different from that of a large position.
It took 6 months to go from 8000U to 3.9U, chasing ups and downs every day, and only stopping losses
It took 1 month to go from 3.9U to 100U, and after seeing the direction, I held on to the end and finally saw the light (mainly because the market has been volatile recently, and it is estimated that it will die miserably if it encounters a one-sided market)
