In the face of trends, all pullbacks are buying signals; don't miss the complete bull market due to short-term fluctuations. Bitcoin rebounded strongly from the low of 74,868, breaking through the 80k level and reaching a high of 81,745. Currently, on the 4-hour chart, the upward channel is intact, the price is above the middle band of the Bollinger Bands, and net capital inflow is nearly 80k, with the bulls fully in control. Although the KDJ is approaching overbought, in a strong trend, overbought conditions will only cause minor pullbacks, not trend reversals. Every pullback is an opportunity for bulls to enter.
