Bitcoin Holds 64% Market Share as Altcoins Struggle
Key Takeaways
In 2025, Bitcoin dominance (BTC.D) reaches 64%. This means that 64% of the total cryptocurrency market value is attributed to Bitcoin. As a result, BTC remains the clear market leader, while altcoins (alternative cryptocurrencies) lose market capitalization. Between January and April 2025, the altcoin market declined by approximately 28% – dropping from $1.13 trillion to $817 billion. Despite this trend, early signs of stabilization are emerging in the altcoin segment.
What Does BTC Dominance Mean?
BTC dominance reflects Bitcoin’s share of the total cryptocurrency market capitalization. When this value rises, capital flows out of altcoins and back into Bitcoin. Historically, strong altcoin rallies have typically coincided with a decline in BTC dominance.
Altcoins Under Pressure – But Finding Support
The altcoin market suffered significant losses in the first quarter of 2025 but appears to have reached a support zone. In particular, the $750 billion level has proven stable. Even smaller altcoins – those outside the top 10 – found support around $200 billion. This level was already an important support area in 2024.
Technical Indicators Point to Possible Recovery
A look at the moving averages (50-week and 200-week MAs) shows that the altcoin market is in a consolidation phase. If the 50-week average is sustainably surpassed, a move toward the next resistance zone around $500 billion could follow. Currently, the market is already 33% above its recent low – an early sign of renewed momentum.
USDT Dominance as an Additional Factor
Another technical indicator is the dominance of Tether (USDT.D). This shows how much capital is parked in stablecoins. A decline in USDT dominance suggests that investors are reallocating their stablecoins into riskier altcoins. At present, USDT dominance is falling from a resistance level at 6%, which could benefit altcoin demand.
Altcoin Season? Not Yet.
The so-called Altcoin Season Index (ASI) is at 18. This value indicates that Bitcoin has significantly outperformed most altcoins over the past 90 days. Only when the index exceeds 75 is it considered a true “Altcoin Season” – which the market is currently far from reaching.

Some Altcoins Defy the Trend
A few altcoins have managed to hold their ground. Monero (XMR) gained 19%, Fartcoin (FARTCOIN) rose by 8%, and PancakeSwap (CAKE) increased by 2.8%. During the same period, Bitcoin lost around 10% in value. These exceptions show that selective opportunities still exist in the altcoin market – despite Bitcoin’s dominant phase.
Our Assessment
The current market situation clearly shows Bitcoin’s dominance. Capital is flowing primarily into the “King Coin,” while altcoins are under pressure. However, early signs of a bottoming process are appearing in the altcoin market. Technical indicators such as moving averages and decreasing USDT dominance support the possibility of a recovery. A true altcoin rally, however, is only likely if BTC dominance declines. Those looking to invest in altcoins should proceed selectively and pay attention to technical signals.
