Bitcoin and Ethereum have entered the fourth quarter of 2025 with weaker performances, registering small losses despite historically strong Q4 returns. According to CoinGlass data, Bitcoin has averaged a 79% return in Q4 since 2013, with Ethereum showing similar trends. However, this year, Bitcoin has declined by 2.4% and Ethereum by 9% over the past month, reflecting slower inflows and market consolidation. Despite the sluggish start, historical patterns indicate a potential rebound in the coming months, driven by ETF inflows and easing monetary policies. Investors remain hopeful that these factors will support a recovery in the final quarter of the year.
