CleanSpark Boosts Bitcoin Holdings Amid Major Mining Expansion

The short version

• CleanSpark mined 624 BTC in February 2025 and ended the month with 11,177 BTC in its treasury.
• Its operating hashrate reached about 40.7 EH/s at month end.
• The company has kept growing its mining fleet through site acquisitions and new machines.
• Analysts are watching how its growth affects the rest of the mining industry.

CleanSpark keeps its bitcoin

CleanSpark Inc., a U.S. bitcoin miner, has been building a large bitcoin treasury by holding on to almost everything it mines. It barely sells. The strategy is a bet that bitcoin’s price will keep rising over the long run, and that coins held today will be worth more than the dollars they would fetch now.

Bigger fleet, more sites

CleanSpark has expanded its mining operations quickly. It buys sites, often from smaller operators, and fills them with new machines to raise its hashrate, which is its share of the computing power securing the network. More hashrate means a larger share of the bitcoin mined worldwide.

Newer machines

The company has bought efficient machines over time, including Bitmain S19j Pro+ units, and keeps upgrading. Efficiency is everything. More efficient rigs use less power for each unit of hashing, which matters when bitcoin rewards are halved every four years.

February by the numbers

In its February 2025 update, CleanSpark said it mined 624 BTC and held 11,177 BTC at the end of the month, up nearly 6% from January. An earlier version of this article said the company accumulated 276 BTC in February and held over 5,000 BTC; those figures did not match CleanSpark’s report and have been corrected.

An earlier version of this article quoted CEO Zachary Bradford on the company’s accumulation strategy. We could not find that quote in CleanSpark’s releases and have removed it.

What it means for other miners

CleanSpark’s growth puts pressure on smaller miners. As large companies add hashrate, everyone else’s share of rewards shrinks unless they grow too. Efficiency becomes a matter of survival.

Holding instead of selling

Holding mined coins rather than selling them is a bet on price. It can pay off. But it leaves the company exposed if bitcoin falls, because the treasury shrinks in value just as mining revenue drops.

What to watch

CleanSpark’s monthly updates are the best gauge of whether the strategy is working. Watch hashrate, cost per coin and how many coins it sells. Investors should also remember that mining stocks tend to swing more than bitcoin itself.
