Bitcoin is facing an unusual mix of short-term bearish and medium-term bullish factors, according to CoinShares research chief James Butterfill. August U.S. core CPI rose 0.3% month on month, exceeding market expectations. Butterfill said the data was marginally negative for Bitcoin because it increased the probability of tighter monetary policy and could limit the asset's immediate upside. CME FedWatch data showed that market expectations for a Federal Reserve rate increase at the next meeting briefly reached 85%.
