September is usually a difficult month for Bitcoin. According to SpotonChain, Bitcoin's performance in September has only been on the rise for three of the past 10 years: 2015 (+ 2.35%), 2016 (+ 6.04%), and 2023 (+ 3.91%). Although September usually falls, it is not inevitable. A negative performance in August could help avoid a decline in September. The main selling pressure has been eliminated. Long-term holders remain firm. Bitcoin ETFs could become a new buying force. Favorable interest rates, capital, and regulation support the market.
