Zhang Zhuoer claims Bitcoin's cycle low is $57,758.

Jiang Zhuoer, founder of the Riverbit mining pool, has called $57,758 the cycle low for Bitcoin (BTC) and said the bull market is "undoubtedly" continuing, arguing that on-chain and long-term indicators show the bear market has ended. He identified $72,500, or the $69,000–$70,000 range, as the zones where the decline could halt, citing Fibonacci retracement levels of 50% and 61.8% respectively. The report did not include the specific indicator values or calculation methods behind his call. The claim matters because it sets a concrete floor for the current drawdown and frames the recent pullback as a buying window rather than a trend reversal. Traders will watch whether BTC holds above $57,758 and whether the $69,000–$72,500 band acts as support or resistance on any rebound.
