Bitcoin Dominance Hits 65% Altcoins May Rally

Bitcoin dominance has reached a significant milestone, hitting 65 percent and approaching its last major ceiling. This level has historically marked turning points where altcoins experienced rapid growth. In 2018 and 2021, similar price levels signaled the beginning of substantial altcoin rallies, leading many traders to believe that the current zone between 64 and 66 percent could soon trigger another altcoin push.

The Bitcoin dominance index, which measures the percentage of the total cryptocurrency market capitalization that Bitcoin holds, has been steadily increasing since mid-2022. This upward trend has brought the index close to historical resistance levels, prompting speculation about an impending shift in capital flow toward altcoins. The chart, which highlights a defined supply zone where BTC dominance previously reversed during major altcoin surges in 2018 and 2021, suggests that the current price action is entering a critical phase.

Historical data shows that when Bitcoin dominance reaches key levels, altcoins tend to outperform. Between July 2018 and January 2021, dominance fell sharply after entering the supply zone, moving from over 70 percent to below 40 percent. A similar trend was observed after BTC dominance spiked in early 2021, only to reverse after hitting just above 73 percent. In each instance, capital flowed into altcoins, causing explosive price movements. The current price action is positioned within the 64–74 percent range, suggesting a possible repeat of history.

Crypto analyst @CryptoYoddha, who shared the chart on July 12, 2025, believes the market is underestimating the potential for altcoin growth. The post reached over 48.5K views within hours, reflecting strong engagement from the trading community. The trendline from early 2023 shows a consistent upward pattern, but momentum may be weakening as BTC dominance nears long-term resistance. If previous trends persist, the crypto market could experience another phase favoring altcoins.

As July progresses, dominance action within this zone will remain a critical signal. Altcoins may see renewed momentum if BTC fails to extend dominance beyond 66 percent. The chart data provides a clear visual reference for monitoring potential reversals, and comments under the tweet echoed growing confidence in altcoin potential. One user noted, “the real pump is coming,” while others pointed to repeated historical patterns as a basis for optimism.
