CleanSpark (CLSK) has added nearly 3,900 Bitmain Antminer S19j Pro miners to its mining fleet, paying $5.9 million, or about $15.50 per terahash, the bitcoin-mining company said in a press release Tuesday.

While many other miners have been in survival mode during the crypto bear market – dealing with not just falling prices, but also surging energy costs – CleanSpark has notably been a buyer of assets at seemingly low prices. With its latest purchase, the company has now acquired more than 26,500 mining rigs in recent months.

The price of $15.50 per terahash is relatively low as mining machines of that efficiency are currently selling at $24.26 per terahash, according to data from mining-services firm Luxor Technologies.

On Monday, liquidity-strapped miner Argo Blockchain (ARBK) said it sold about the same number of mining rigs as CleanSpark bought.

CleanSpark has also been a recent buyer of data-mining centers, including two facilities in the state of Georgia, where the company mainly operates.

Last week, CleanSpark boosted its estimate for its year-end hashrate, or computing power, by 10%.
