BTC & Altcoin Dominance

BTC and Altcoin Dominance – April and May have seen steady growth in BTC dominance, countered by a slow decline in altcoin dominance. This is reflected in BTC spot, which is up nearly 14% over the last three months, whereas large-cap altcoin spot, such as Ethereum and Solana, are up 6.9% and 0.6% over the same period, respectively. This marks a large contrast to historical instances where altcoins have served as a leveraged expression of broader crypto sentiment.

ETF Flows: BTC, ETH & Altcoins

ETF Flows – BTC and ETH ETFs saw heavy outflows over the past week, with BTC products losing $1.00B and ETH products losing $255.11M. The weakness came alongside softer major-token performance.

Altcoin ETFs showed a different picture, with demand remaining broadly positive across the group.

XRP and SOL led inflows at $60.50M and $58.12M, respectively, while LINK, HYPE, HABR, DOGE, and AVAX also recorded smaller inflows. This points to continued interest beyond BTC and ETH, with altcoin products attracting capital despite broader market pressure.
