Bitcoin has gained roughly 43.5% in Q3 2026, placing it on course for its second-strongest third quarter. Only the 80.41% gain recorded in 2017 ranks higher, while Bitcoin’s current return has already surpassed 2013’s 40.6% increase. According to CoinGlass, the advance follows losses of 22.2% in Q1 and 14.09% in Q2, reversing Bitcoin’s earlier quarterly pattern. Data from CoinGecko placed BTC near $84,800, although September’s remaining sessions could alter its final quarterly ranking.
