Two Largest DAT Companies Double Down on Crypto Buys

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 weeks 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 Lees 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.
