Bitcoin’s share of the total cryptocurrency market capitalization climbed past 61 percent this week, a multi-year high that signals a growing divergence between the world's largest digital asset and the broader altcoin market. Bitcoin's price reached $81,054 while Ethereum traded at $2,324.
"BTC’s rally was supported by both strong demand and constrained supply," a recent report from Japanese DeFi asset management platform XWIN noted. In contrast, the firm’s analysis showed Ethereum's market has been more influenced by erratic exchange netflows, resulting in a reactive, supply-driven structure rather than the demand-led growth seen in Bitcoin.
The divide is further evidenced by on-chain data from CryptoQuant, which shows a higher Coinbase Premium Index for Bitcoin, indicating stronger institutional buying pressure compared to Ethereum. This institutional preference is a key factor in Bitcoin's outperformance, with Bitcoin’s Exchange Netflow chart showing more outflow spikes—a sign of sustained accumulation and decreased selling pressure. The ETH/BTC ratio has also declined by 4.37% over the past month, reinforcing the trend of capital rotating towards Bitcoin.
This growing dominance by Bitcoin is putting a damper on hopes for an "altseason," a period where alternative cryptocurrencies outperform Bitcoin. Until Ethereum begins to show sustained spot demand similar to Bitcoin, capital is likely to continue consolidating into the benchmark asset, prolonging the underperformance of the broader altcoin market.
