I personally think that the current rebound of Btc 74500 to 111980 has ended, and it is now entering a volatile downward trend. Surprisingly, the trend has reversed, so 100700 is not the bottom, and there are even lower levels. However, short selling is not easy to do, as it will repeatedly insert and insert false breakthroughs and false drops to truly break the level. It tests the mentality, try to do intraday orders as much as possible, short selling in small cycles is the right way, and the winning rate is much higher than going long at the support level
