Bitcoin surged from the morning to 63,674, then faced resistance and pulled back, followed by oscillating downward, quickly dropping to the intraday low of 61,067 which triggered buying support, leading to a quick rebound. The rebound failed to re-enter above the Bollinger middle band at 62,444, and the price again oscillated downward, closing near the 62,000 level at the end of the session.

Key short-term resistance is at the first level of 62,440, the Bollinger middle band; next are the upper band at 63,160 and the intraday high at 64,460. Short-term support levels are at the Bollinger lower band at 61,720, a strong support at the intraday low of 61,067, and a break below would open the door to deeper downward space.
From a short-term perspective, the main trend is bearish for the day, but the low KDJ crossover indicates a small technical rebound demand. The rebound should first test the middle band resistance. If the rebound cannot hold above 62,440, it is likely to continue the weak trend, testing the Bollinger lower band and the intraday low.
