Judging from the daily trend of Bitcoin, the K line pulled up three consecutive positives, broke through MA120 in one fell swoop, and returned to the upward trend line. However, there has been a second deviation at the small cycle level from 15 minutes to 30 minutes. Beware of short-term surges and declines. If you want to enter a long order, you must at least wait for BTC to fall back to around 27500, and then it will be more stable.
