Ether rallied above $4,200 on 10 August, lifting Ethereum’s market capitalization to roughly $515 billion, according to multiple crypto-market data trackers. The advance restores a valuation last seen during the 2021 bull run and pushes the token’s standing among the world’s largest assets into the global top 25. The latest move means Ethereum has overtaken Mastercard in market value, making it the 22nd-largest asset globally and the second-largest cryptocurrency after Bitcoin. Data provider stats_feed placed Ethereum’s market cap at about $511.5 billion earlier in the session, underscoring the rapid appreciation over the past 24 hours. The rally has also returned Ethereum co-founder Vitalik Buterin to billionaire status on-chain: the balance held in his publicly disclosed wallet now exceeds $1 billion. Separately, reserves held by spot exchange-traded funds tracking Ether have climbed to around $25 billion, signaling sustained institutional demand.
