Bitcoin analyst Willy Woo identified a significant technical signal using the Fisher Transform indicator, noting that its two trend lines crossed upward during July at -2.26. This event marks only the fourth such occurrence on record for Bitcoin, with previous instances corresponding to bear-market bottoms on monthly time frames. The indicator, created in 2002, smooths price action to reveal trend strength by correcting statistical biases in extreme values.

While this crossover historically precedes macro uptrends, Woo cautioned that consolidation or further declines remain possible due to speculative trader activity influencing momentum. On weekly charts, a bullish divergence emerged as the indicator hit a swing low of -2.85 in late December while Bitcoin traded near $90,000. Despite these signals, doubts persist regarding whether the July lows near $57,000 represented a definitive cycle bottom, as bid-side activity showed limited broad buyer interest.
