Bitcoin dominance weakens again – Will 2017 and 2021 history repeat?

Bitcoin dominance (BTC.D) has begun to weaken after reaching the 60% zone during the recent market expansion. That slowdown suggests capital concentration around Bitcoin may gradually be fading.

Earlier cycles have shown similar transitions across broader cryptocurrency markets.

During 2017, dominance collapsed from nearly 95% toward 35% as Ethereum [ETH] and smaller-cap assets absorbed rising liquidity. That rotation later fueled one of crypto’s strongest altcoin rallies.

A similar pattern reappeared through 2021.

Dominance briefly climbed near 70% before sharply reversing below 40% as speculative appetite expanded beyond Bitcoin [BTC]. Meanwhile, Bitcoin continued rallying toward the $60,000 region, showing capital rotation can coexist with broader market strength.

However, falling dominance also increases volatility exposure. If liquidity weakens again, speculative capital may quickly retreat from altcoins back toward Bitcoin and stable assets.

Capital rotation deepens beyond Bitcoin leadership

As BTC.D gradually lost momentum, liquidity started flowing deeper into the broader altcoin market.

Adding to this, AMBCrypto had earlier reported on falling Tether [USDT] and BTC. D further reinforced this shift, signaling capital was rotating into altcoins instead of remaining concentrated in defensive assets.

That shift became clearer through 2024 and 2025 as the volume ratio steadily pushed above 0.30, signaling expanding participation beyond Bitcoin, Ethereum, Solana [SOL], Ripple [XRP], and BNB.

Earlier cycles reflected similar market behavior.

During 2021, the ratio surged beyond 1.5 while Ethereum rallied near $4,800. That expansion showed speculative confidence was strengthening as traders increasingly rotated toward smaller-cap assets for higher returns.

As yellow clusters intensified, short-term altcoin volume repeatedly exceeded the yearly average.

This reinforced that capital rotation was becoming sustained rather than temporary, while broader market participation steadily deepened beneath the surface.

However, overheated conditions also increased fragility. Once liquidity tightened during 2022, the ratio collapsed below 0.20 as speculative capital rapidly retreated.

Early altseason signals clash with Bitcoin’s market control

As liquidity slowly rotated beyond Bitcoin, altcoins started attracting broader yet cautious market participation.

However, most activity still leaned heavily toward leveraged trading instead of sustained spot accumulation.

Meanwhile, Bitcoin dominance remained near 60%, while the Altcoin Season Index stayed below the 75 altseason threshold. This showed Bitcoin still controlled broader market direction despite selective rallies across DeFi and Layer-1 ecosystems.

Stablecoin supply also held above $320 billion, signaling strong sidelined liquidity beneath the market. Yet weak capital retention after rallies suggested confidence still faded quickly whenever Bitcoin regained stronger momentum.

Final Summary

• Bitcoin dominance (BTC.D) weakens as altcoin liquidity expands, though leveraged speculation still outweighs sustained spot-driven market conviction.
• Altcoin participation continues broadening beneath the surface, yet stronger Bitcoin leadership could still rapidly absorb emerging market liquidity.
