Bitcoin (BTC) has dominated the crypto market for the past two years, surging to an all-time high near $120,000 while major altcoins like Ethereum (ETH) and Solana (SOL) lagged behind their 2021 peaks. From December 2022 to June 2025, BTC’s market dominance climbed steadily from under 40% to 65%. However, that trend reversed sharply this July, with bitcoin dominance falling 5.8% in just one week — its biggest drop since June 2022.
According to CoinGecko data, the altcoin market is showing strong momentum. Most of the top 100 tokens have posted gains between 20% and 30% in the past week. ETH surged 26%, DOGE climbed 40%, XRP gained 22%, ADA rose 23%, and SOL jumped 7% today alone, bringing its weekly gain to 18%.
Brian Rudick, chief strategy officer at SOL-focused treasury firm Upexi, attributes this shift to growing support for U.S. digital asset legislation. “This is likely to boost on-chain development, which favors altcoins more than bitcoin,” he told CoinDesk. He noted a rising number of digital asset treasury firms are moving beyond BTC into ETH, SOL, and newer tokens.
Recent activity supports this trend. DeFi Development expanded its SOL holdings to nearly $200 million, while Bitmine and SharpLink are competing over ETH accumulation. ETH treasury firm The Ether Reserve is rebranding as The Ether Machine and plans to list on Nasdaq. Newcomer StablecoinX is building a treasury based on Ethena’s ENA token.
Despite heavy BTC investments — such as $740M from Michael Saylor, $150M from Sequans, and $2B disclosed by Trump Media — altcoin market caps remain smaller, meaning new capital flows have a greater impact. If regulatory progress continues, analysts expect BTC dominance to fall further as altcoin season strengthens.
