$BTC fell to 60600 and rebounded, which is about the position I expected. The current important support levels are 60800 and 59600. The trend line shows that it has the intention of breaking upward. I think the trend of BTC in the next period of time tends to fluctuate in a narrow range. Because the volatility in the previous period was too high, the volatility has obviously begun to converge in the past few days.
