Bitcoin is down 1.5% in September, a historically weak month for the cryptocurrency, according to CoinDesk. Despite the monthly decline, Bitcoin remains on track to post its first quarterly gain in a year. The market has been tested by several macroeconomic pressures, including rising interest rates, surging oil prices and a stronger U.S. dollar. Bitcoin has also faced a setback related to the Clarity Act, adding to the challenges confronting bullish market participants. The limited September decline means the cryptocurrency has so far held up relatively well against the broader combination of financial and policy headwinds.
