Mars Finance News, on March 31, since Bitcoin's block reward halving last year, Ethereum has underperformed Bitcoin, which is the first time this has occurred. The ETH/BTC exchange rate dropped to a five-year low of 0.02193. This year, Ethereum has declined 39% relative to Bitcoin. In May 2020, Ethereum was priced around $200, with Bitcoin slightly below $10,000. Now, Ethereum is priced around $1,800, and Bitcoin is around $82,000. The current downturn echoes the poor performance in 2019, further highlighting Ethereum's relative weakness, especially compared to other Layer 1 assets. The SOL/ETH exchange rate has risen 24% year-to-date to 0.07007. This indicates that despite the SOL token itself declining 35% year-to-date, SOL's performance is significantly better than Ethereum's in 2025.
