On September 22, according to Cointelegraph, the Federal Reserve's interest rate cut last week was regarded as an important boost to Bitcoin's rise, but the market did not rise because of this, which suggests that the Bitcoin bull market cycle may be coming to an end. Alphractal founder Joao Wedson posted on X on Monday: Bitcoin has shown signs of running out of cycle, but few people have noticed it. Signals on multiple chains indicate that Bitcoin's rebound may have lost momentum. Bitcoin's used output profit margin (SOPR, a measure of the overall profitability of all spent bitcoin transactions on the blockchain) shows a decline in profitability, increasing the possibility of a deeper correction. The Sharp ratio is lower than the 2024 level, which means that risks and returns and profit potential are reduced. Wedson added: It won't attract as many institutional investors as most people think. Even if Bitcoin hits a new high, profitability will remain low and the real focus will shift to altcoins.
