Bitcoin's B wave rebounded to a high of 111,800, close to the 0.236 retracement level of Wave A. Referring to Bitcoin's previous leading diagonal triangle, this is an appropriate rebound position for Wave B after the completion of Wave A's leading diagonal triangle. Therefore, the B wave rebound may be nearing completion. The key upward resistance level is the August 28 high of 113,500. As long as the rebound does not break through this resistance level, we maintain our prediction that BTC will fall to near the annual line.
