On December 17, on-chain analyst Murphy said Bitcoin’s chip concentration—holdings within 5% of the spot price—stands near 11%, a moderately high level but below the 13% warning line and 15% high-risk zone. He said this structure limits the likelihood of near-term chain reactions or sharp price moves. Murphy added that upcoming events, including the December 18 CPI release and the Bank of Japan’s December 19 rate decision, should cause only minor volatility if expectations are met, unlike the sharp move seen in August 2024 when concentration hit 15%.
