Bitcoin and Ethereum are leading the pack in terms of performance, with gains of +17.6% and +18.2% year-to-date, respectively. Ethereum has recently started to outperform Bitcoin after the approval of the Bitcoin ETF, a change from its previous underperformance.
Meanwhile, the overall Altcoin market cap hasn't seen the same level of growth, with gains less than half of what Bitcoin and Ethereum have achieved so far this year.
