Ether Is Up 25% Week to Date and On Pace for Its Best Week Since May 2021

Ether is up 25% week to date and on pace for its best week since May 2021. The Solana token has added 14.3% this week, which is on track to be its best week since January.

Year to date, however, ether and other major altcoins – with the exception of XRP – are still deep in the red compared to bitcoin. While the flagship crypto is up 10%, ether and the Solana token are down 31% and 12%, respectively.

Bitcoin's market structure changed after the introduction of spot bitcoin ETFs in 2024, with demand now coming from retirement accounts, macro funds, and corporate bonds such as Strategy. By contrast, altcoins still rely on crypto-native, risk-on capital, which hasn't shown significant growth alongside the greater tech sector due to the current interest rate environment, according to Eric Chen, Co-Founder of Injective.

Bitcoin is likely to keep outperforming until broader capital flows into altcoins, he added, given their steady supply and lack of a structural buyer base, which are likely to take prices lower until they attract speculative interest.

"For us, there remains one singular strategy for crypto investors: stick to BTC until risk on headwinds dissipate," Wolfe Research analyst Read Harvey said in a note this week. "The coin is one of just two in our basket positive on the year and it continues to dominate the rest of the space on a relative basis. The question now shifts towards if it can maintain recent outperformance vs. equities, or if Gold was right all along."
