Strategy just bought nearly 6x more BTC than last week, while Tom Lee’s Bitmine also purchased more ETH than usual.
The largest digital asset treasury (DAT) companies for Bitcoin (BTC) and Ethereum (ETH) added more crypto than usual to their stockpiles last week.
Michael Saylor’s Strategy announced on Monday, March 9, that its latest weekly Bitcoin purchase totaled 17,994 BTC at an average price of about $70,946 per coin. Last week’s buy is nearly 6x larger than the previous week’s buy of 3,015 BTC — which itself marked a notable uptick in accumulation after weekly buys shrank since late January.
The latest purchase bring’s Strategy’s stockpile to 738,731 BTC as of March 8, or about $50.65 billion at current prices. The publicly traded firm remains the largest Bitcoin DAT by holdings, followed by MARA Holdings with 53,822 BTC.
Meanwhile, the second largest DAT company and the largest Ethereum DAT, Tom Lee’s Bitmine Immersion Technologies, announced in a press release today its most recent purchase of 60,976 ETH, bringing its total Ethereum holdings to 4,534,563 ETH as of March 8.
Per the release, last week’s purchase is well above the firm’s recent weekly purchase average of 45,000-50,000 ETH. The previous week, Bitmine bought 51,000 ETH. Bitmine is currently staking 3,040,483 ETH, or about 67% of the 4.5 million ETH that it holds in its treasury.
Also today, the second-largest Ethereum DAT, Sharplink, released its 2025 financial report. Per a press release from the firm, it recorded a $734.6 million net losses last year, a solid chunk of which — $616.2 million — were unrealized losses on its ETH holdings.
Sharplink announced its rebrand to an Ethereum DAT in May of last year — with Consensys CEO and Ethereum co-founder Joseph Lubin as chairman of its board. The firm has accumulated 864,840 ETH to date, at an average cost of $3,588 per ETH, per CoinGecko data.
But, the spot price of ETH had a volatile year in 2025. ETH reached a new all-time high near $5,000 in August, only to end the year struggling near $3,000. ETH is currently trading just over $2,000 at publishing time.
