Crypto stocks suffered a red day on Friday, especially bitcoin BTC treasury companies such as Strategy (MSTR) and Semler Scientific (SMLR) — each down roughly 6% even as bitcoin slipped only a bit more than 2%. Japan-listed Metaplanet is lower by 24%.

The picture looks even worse when zooming out: changing hands at $376 early Friday afternoon, MSTR shares are more than 30% below their all-time high hit late in 2024 even as bitcoin has pumped to a new record this week.

The price action comes amid a continuing debate taking place on social media about the sustainability of Michael Saylor’s (and those copycatting him) bitcoin-vacuuming playbook.

“Bitcoin treasury companies are all the rage this week. MSTR, Metaplanet, Twenty One, Nakamoto,” said modestly well-followed bitcoin twitter poster lowstrife. “I think they’re toxic leverage is the worst thing which has ever happened to bitcoin [and] what bitcoin stands for.”

The issue, according to lowstrife, is that the financial engineering that Strategy and other BTC treasury firms are employing to accumulate more bitcoin essentially rests on mNAV — a metric that compares a company’s valuation to its net asset value (in these cases, their bitcoin treasuries).

As long as their mNAV remains above 1.0, a given company can keep raising capital and buying more bitcoin, because investors are showing interest in paying a premium for exposure to the stock relative to the firm’s bitcoin holdings.

If mNAV dips below that level, however, it means the value of the company is even lower than the value of its holdings. This can create significant problems for a firm’s ability to raise capital and, say, pay dividends on some of the convertible notes or preferred stock it may have issued.

Shades of GBTC

Something similar happened to Grayscale’s bitcoin trust, GBTC, prior to its conversion into an ETF. A closed-end fund, GBTC during the bull market of 2020 and 2021 traded at an ever-growing premium to its net asset value as institutional investors sought quick exposure to bitcoin.

When prices turned south, however, that premium morphed into an abysmal discount, which contributed to a chain of blowups beginning with highly-leverage Three Arrows Capital and eventually spreading to FTX. The resultant selling pressure took bitcoin from a record high of $69,000 all the way down to $15,000 in just one year.

“Just like GBTC back in the day, the entire game now — the whole thing — is figuring out how much more BTC these access vehicles will scoop up, and when they will blow up and spit it all back out again,” Nic Carter, partner at Castle Island Ventures, posted in response to lowstrife’s thread.

The thread also triggered replies from MSTR bulls, among them Adam Back, Bitcoin OG and CEO of Blockstream.

“If mNAV posted. “Or people see that coming and don’t let it go there. Either way this is fine.”
