BTC has already risen quite a bit. To keep going higher, it should go through a pullback first. A rise is a healthy uptrend only when it happens in a way that’s followed by a retracement. After BTC broke out of the flag pattern, it was capped and suppressed by the 65,633 resistance; the rebound failed to follow through, and around the 65,633 resistance area it formed a shooting star / evening star pattern (the white box marks the circled spot). The presence of an evening star suggests there is a need for a pullback. After that, BTC fell back into the flag pattern and tested the support at the lower boundary of the flag, 64,494. Since the support was confirmed as effective, the sell-off didn’t expand.
