Two of the biggest public-company crypto treasuries are taking very different roads. Strategy (MSTR) keeps stacking Bitcoin — roughly 818,000 BTC as of late April, bought at an average of $75,000 and now supporting a market cap near $60 billion. BitMine Immersion Technologies (BMNR) has gone the other way: it holds nearly 5 million Ether (about 4.12% of total supply) plus $1.1 billion in cash, with a market cap around $12 billion. The split matters because the underlying economics aren't the same.
How each treasury works
Strategy's flywheel is familiar by now. It raises money through common-stock ATM programs, low-coupon and zero-coupon convertible notes, and perpetual preferred securities — the latest being STRC, which pays an 11.5% monthly cash dividend. That cash goes into Bitcoin. Bitcoin pays nothing back. So Strategy has to keep layering on more financing instruments to create the return that investors expect. Michael Saylor has talked about targets in the millions of BTC, with no ceiling in sight.
BitMine does something simpler. It holds Ether, but it also stakes roughly 3.3 million of it through Ethereum's proof-of-stake mechanism, earning about 2.8% APY. That staking yield turns a static treasury into an income-producing asset. The company doesn't need to issue convertible notes or perpetuals to generate a return — the blockchain does it automatically.
The yield advantage Ethereum gives BitMine
Bitcoin has no native yield. Strategy compensates by using financial engineering that, in bull markets, lets it trade at mNAV premiums of 1.5x to 2.5x. But those premiums depend on market sentiment and the appetite for increasingly exotic instruments. BitMine, by contrast, has a structural yield baked into its core asset. Ethereum's staking yield isn't huge — 2.8% — but it's consistent and doesn't require new debt or equity issuance.
The market hasn't fully rewarded BitMine for that yet. The stock has traded near or below net asset value parity, with mNAV ranging from roughly 0.93x down to 0.6x–0.7x. Strategy has historically commanded a premium, but the gap suggests investors may be discounting BitMine's income stream — or simply favoring Bitcoin's brand.
What this means for the two stocks
Strategy's approach is proven in a rising market. When Bitcoin rallies, the leverage from its debt stack amplifies returns. But when sentiment sours, the financing costs and the need to keep rolling over paper become a risk. BitMine's model is less volatile: the staking yield provides a floor of organic income, and the cash pile gives it options. The question is which one holds up better if crypto markets turn choppy later this year.
No one is expecting Strategy to stop buying. Saylor has framed the accumulation as open-ended. BitMine, meanwhile, can let its Ether sit and earn. The next real test will come when a bear cycle tests both structures — and for now, only one of them has a built-in income buffer.
