$BTC Rebound lacks momentum, beware of pullback, short on rallies

BTC rebounded on the fourth day, but failed to break through the 72000 resistance level. The highs have been declining progressively, and the 4H chart has formed a converging triangle pattern. The market is still within the daily-level oscillation range. If it cannot break through 72000 for an extended period, it will inevitably search for support lower.
Strategy: Long positions at low levels should take profits, bears should short on rallies.
