Bitcoin dominance has begun losing momentum following a prolonged uptrend, drawing fresh attention from analysts and traders.
A bearish MACD crossover on the BTC dominance chart has triggered wide speculation. Many market observers now believe capital is starting to rotate into altcoins.
Throughout the first half of 2026, Bitcoin led the crypto market almost entirely on its own. Whether this shift marks a temporary pullback or the start of a broader altseason remains the central question.
For most of early 2026, Bitcoin absorbed the majority of crypto market inflows. Spot BTC ETF demand, institutional buying, and macro uncertainty pushed BTC dominance close to 60%. During this period, most altcoins struggled to keep pace with Bitcoin’s performance.
However, conditions appear to be changing beneath the surface. Crypto Quant analyst CryptoOnchain recently pointed to a key metric called the “Altcoin Volume Increasing Trend.”

This signal appears when the 30-day average altcoin trading volume crosses above the 365-day average. It measures the CEX Volume Ratio between Others and the Top 5 assets.
Historically, this pattern has appeared before major altcoin rallies. During the 2021 cycle, similar signals preceded strong runs in ETH and smaller-cap tokens. That context has given analysts reason to take the current reading seriously.
Price action is beginning to reflect early rotation as well. While ETH has held relatively steady, SOL and SUI have posted notable double-digit gains recently. These moves suggest capital may already be moving beyond Bitcoin into the broader market.
Beyond volume data, on-chain metrics are painting a broader picture. Indicators such as Profit/Loss Margin and MVRV remain well below previous cycle peaks. This suggests the current bull market has not yet reached the levels of excess seen in prior tops.
Long-term holders are also showing limited selling behavior at this stage. Historically, sustained distribution from long-term holders has preceded major market tops. The current restraint from this group points to continued confidence in further upside.
Looking back at the long-term BTC Market Cap Dominance chart adds further context. Both the 2017 and 2021 cycles saw dominance decline sharply before altcoins rallied hard. Capital rotated from BTC into ETH first, then spread into smaller assets, triggering broader market gains.
The pattern forming today shares structural similarities with those prior cycles. That said, past performance does not guarantee future outcomes.
Traders are now watching closely to see whether BTC dominance recovers or continues its decline into a confirmed altseason.
