Not enough drop, 4214 was sold in batches. If Bitcoin wants to drop and the market is divided, then it's likely to be volatile. Don't be narrow-minded.

Today, there was a volatile decline back to 4160-4060. Tomorrow, there will be a volatile rise to 4380, and then there will be fluctuations between 4380-4480 (lasting 7-10 days) with a high point of 4580 and a low point of 4260. Both bulls and bears have opportunities; within the range, sell high and buy low. Don't think about the pattern of 50-90 points; take profits where appropriate (giving yourself advice for future operations).
