Strategy selling? Saylor’s Bitcoin transfer to Coinbase puts his treasury model under cash pressure

On May 29, Strategy (formerly MicroStrategy) moved more than 411 Bitcoin to Coinbase Prime, drawing fresh scrutiny to Michael Saylor’s financing model.

Arkham Intelligence data showed two transfers of roughly 205.3 BTC and 206.2 BTC from Strategy-associated wallets before the coins reached the destination address.

This movement has not been confirmed as a sale, and Strategy has previously shifted coins between wallets as part of custody management, triggering similar speculation that later appeared to reflect internal restructuring.

However, the latest transfer drew closer attention because of how the coins moved.

ForeDex Proof, an on-chain analyst, said the transferred Bitcoin first left two Strategy-linked wallets for new addresses before being moved again, a second step that differs from earlier wallet migrations.

Those prior transfers generally stopped after funds moved from an MSTR-linked wallet into a new address.

Moreover, the address format also stood out. ForeDex Proof said Strategy has historically used Coinbase Custody and Native SegWit addresses beginning with “bc1q,” while the latest movement involved an address beginning with “3,” a P2SH format.

Considering this, the analyst said the latter wallets appeared connected to Coinbase Prime activity commonly associated with over-the-counter transactions, raising the possibility that Strategy was preparing to sell a small portion of its holdings.

Still, this BTC movement represents only a fraction of Strategy’s 843,738 BTC treasury, but its timing gave the movement greater weight.

This is because it came during a week in which the company paused fresh Bitcoin purchases, moved to repurchase convertible debt, and told investors that selling Bitcoin could become part of its financing toolkit if market conditions or dividend obligations required it.

STRC stress narrows Strategy’s room for error

The Coinbase-linked transfer comes as Strategy’s preferred-stock structure faces pressure from a falling dollar reserve and weaker trading in STRC, the variable-rate preferred instrument designed to trade around its $100 par value.

Over the past months, Strategy has used the preferred stock issuance as part of a broader funding system that enables it to raise capital, buy Bitcoin, and manage liabilities without relying solely on common stock or convertible debt.

Market observers noted that STRC’s structure depends on market confidence, as investors must believe the company can continue paying dividends, maintain sufficient cash coverage, and access capital markets.

That confidence has grown more fragile as STRC has consistently traded below par since mid-month.

Meanwhile, Strategy recently moved to repurchase nearly $1.5 billion in face value of its 0% convertible senior notes due in 2029 for about $1.38 billion in cash.

The repurchase removed a future liability and retired the notes at a discount, but it also reduced the reserve that some investors had viewed as a buffer for preferred dividends and interest costs.

Glenn Cameron, global head of institutional at Onramp Bitcoin, said Strategy’s dollar reserve fell from $2.25 billion on Feb. 1 to $871 million on May 25. The decline roughly matched the cash cost of the convertible-note repurchase.

Cameron estimated that Strategy’s annual cash obligation is about $1.66 billion, including preferred dividends, convertible interest, and software business burn. He said STRC alone accounts for about $1.23 billion of that total at an 11.5% dividend rate.

On that estimate, Strategy’s remaining dollar reserve covers about 6.3 months of annualized obligations. Cameron said the reserve had been presented to STRC subscribers as roughly 2.5 years of coverage for preferred dividends and interest on debt before the convertible repurchase reduced the cash cushion.

These figures sharpen concern over the company’s funding structure. If STRC remains below par, Strategy may need to raise the dividend rate to restore demand, and each increase applies to the full outstanding STRC stack, raising the company’s future cash burden.

Crypto analyst Ragnar said Strategy needs to refill its cash reserve as soon as possible and argued that STRC’s weakness may reflect investor concern over the shrinking coverage ratio.

He said the company may sell higher-cost Bitcoin lots to rebuild cash, citing purchases of 220 BTC at $123,561, 430 BTC at $119,666, and 6,220 BTC at $118,940 as potential candidates if Strategy chooses to reduce exposure at the margin.

That theory would align with the logic of a tactical sale without altering Strategy’s broader holdings. Selling higher-cost coins could raise cash and reduce the company’s average cost basis while leaving the bulk of its treasury intact.

It would also mark a visible change in the way investors understand Saylor’s Bitcoin strategy, because even a limited sale would show that some coins can be used to support the capital stack when market conditions tighten.

Strategy faces a 4-month window

Joao Wedson, chief executive of Alphractal, said the pressure reflects a deeper issue around Strategy’s accumulation timing.

He argued that a company with such a large Bitcoin position should have built a much lower average entry price during the 2022 and 2023 bear-market window, rather than carrying an average purchase price near the mid-$70,000 range after aggressive buying in 2024 through 2026.

Wedson said older Bitcoin holders were distributing during the later phase of Strategy’s accumulation, leaving the company with a less favorable risk-reward profile.

His critique cuts into one of the assumptions behind the model: that repeated capital raises can keep improving shareholder exposure as long as the company converts proceeds into Bitcoin.

That argument has become more relevant as preferred dividends grow. A lower average cost basis would give Strategy more flexibility to sell a limited amount of Bitcoin while still realizing gains across the treasury.

However, a higher cost basis leaves less room between market price, investor confidence, and the obligations attached to the company’s preferred-stock stack.

Jeff Dorman, chief investment officer at Arca, said Strategy has entered its first major bind among common shareholders, Bitcoin holders, and preferred investors.

He argued that the company could have preserved its cash buffer for dividend payments, but instead used a large portion of that reserve to retire 0% of its debt.

Dorman said the company now faces two main paths if pressure continues. It can sell Bitcoin to help fund preferred dividends, supporting preferred holders while weakening the accumulation narrative. Or it can stop paying dividends, preserving the Bitcoin stack while undermining confidence in the preferred securities.

Strategy could also raise new capital, but that depends on market access. STRC’s design relies on the ability to issue securities near par. If investor demand weakens, the company may need to offer higher yields to attract buyers, thereby increasing future obligations against the same Bitcoin pool.

Dorman said the tension could play out over the next four months. That timeline has become a test of whether Strategy can keep its funding loop intact while Bitcoin remains volatile, STRC trades below par, and the dollar reserve provides less room for error.
