According to CoinMarketCap, BitMine purchased 96,798 ETH for roughly $273 million last week. CoinMarketCap reports the entity now holds 3.73 million ETH worth about $10.5 billion, exceeding 3% of the Ethereum supply. Based on CoinMarketCap’s figures, the weekly buy implies an average fill near $2,821 per ETH and represents about 0.08% of total supply absorbed in the period. Using CoinMarketCap’s $10.5 billion valuation, a 1% ETH price move would shift the position’s mark-to-market by roughly $105 million, which is a notable risk metric for position sizing. For trading reference, CoinMarketCap’s reported average fill near $2,821 can serve as a cost-basis level to monitor reactions around that zone.
