Market data shows that Ethereum, the king altcoin, has dramatically closed in on Bitcoin’s annual performance following Q3 gains.
Ethereum has nearly matched Bitcoin’s annual performance over the last quarter, according to a chart shared by CryptoQuant analyst Axel Adler Jr. This comes as both assets hit all-time highs this year.

By May 2025, Bitcoin’s upward run resumed, hovering consistently above 50% performance gains. Ethereum, though still lagging during the mid-year period, began a rapid recovery from July, lifting its yearly performance back into positive territory.
By September, the gap between the two had nearly closed, showing synchronized rallies that drove the correlation to near-perfect levels.
Ethereum Could Be Bitcoin’s Replacement
Analyst Merljin also backs up the analysis, emphasizing Ethereum’s current bullish push. According to the market watcher, the ETH/BTC ratio has broken above a long downtrend, potentially positioning Ethereum for its strongest relative rotation against Bitcoin since 2017.
