The best-known corporate Bitcoin case studies, MicroStrategy (now Strategy), Tesla and Block, show three different ways a company can approach Bitcoin on its balance sheet. One made it the centre of its corporate strategy, one made a large tactical purchase and later sold most of it, and one made a measured allocation linked to its business. Each offers lessons in governance rather than in timing.
We use only well-established public facts here, with dates. We do not quote holdings or prices that change over time. Our short history of institutional Bitcoin adoption puts these cases in the wider timeline.
Case study 1: MicroStrategy (now Strategy)
What happened
In August 2020, MicroStrategy, a US-listed business intelligence software company, announced that it had bought US$250m of Bitcoin and adopted it as its primary treasury reserve asset. It made further purchases in the following weeks.
From December 2020, it began issuing convertible notes and later used other capital-raising instruments to buy more Bitcoin. Over the following years, Bitcoin became the defining feature of the company's equity story. It renamed itself Strategy in 2025.
What it shows
- A full strategic commitment. The company did not treat Bitcoin as a side allocation. It changed how investors valued the whole business.
- Funding shapes risk. Moving from cash to debt and equity funding turned a treasury decision into a capital structure strategy.
- Clear communication. The company explained its rationale publicly and repeatedly, which shaped the shareholder base it attracted.
- Accounting friction. Under the rules then in force, Bitcoin was an indefinite-lived intangible asset. The company reported impairment losses when prices fell but could not record gains when they rose.
This model is now associated with Bitcoin treasury companies, and with metrics such as mNAV.
Case study 2: Tesla
What happened
In February 2021, Tesla disclosed in its annual report that it had bought US$1.5bn of Bitcoin, and said it expected to begin accepting Bitcoin as payment for its products. In May 2021 it suspended Bitcoin payments, citing concerns about the energy used in mining.
In its results for the second quarter of 2022, Tesla disclosed that it had converted most of its Bitcoin holdings into fiat currency. It retained a smaller holding.
What it shows
- Tactical rather than strategic. The purchase was presented as part of broader treasury flexibility, not as a long-term reserve with a fixed mandate.
- Reputation is a live risk. The payment decision, and its reversal, drew more attention than the investment itself. Mission and stakeholder considerations can change quickly.
- Selling is a valid outcome. A company can decide that a holding no longer fits its needs. Clear sell criteria make that decision easier to explain.
- Impairment accounting again. Under the pre-2023 rules, Tesla recorded impairment charges on the holding in periods when the price fell.
Case study 3: Block (formerly Square)
What happened
In October 2020, Square, the payments company later renamed Block, announced a US$50m Bitcoin purchase, described at the time as around 1% of its total assets. In February 2021 it announced a further purchase of US$170m.
The company linked the holding to its business: it already offered Bitcoin buying and selling to its consumers and had a stated view on Bitcoin's role in its products.
What it shows
- Sized as a share of assets. Expressing the allocation as a percentage of total assets gave investors a clear sense of scale and risk.
- Strategic fit. The holding was consistent with the company's products and published views, which made it easier for shareholders to understand.
- Measured pace. Two discrete purchases, each announced with its rationale, rather than a continuous programme.
CFO tip: before any board discussion, ask which of these three paths your company most resembles, and why. It is a quick way to surface the assumptions directors are bringing into the room.
The three corporate Bitcoin case studies compared
| MicroStrategy / Strategy | Tesla | Block | |
|---|---|---|---|
| First disclosure | August 2020 | February 2021 | October 2020 |
| Initial size | US$250m | US$1.5bn | US$50m |
| Framing | Primary treasury reserve asset | Treasury flexibility | Share of total assets, tied to business |
| Later funding | Convertible notes and other capital raising | Not applicable | Further purchase in February 2021 |
| Subsequent path | Bitcoin became the core strategy | Most holdings sold, disclosed in 2022 | Held as a measured allocation |
Lessons for CFOs today
The environment has changed since 2020. ASU 2023-08 now requires fair value measurement under US GAAP for fiscal years beginning after 15 December 2024, ending the impairment-only problem. US spot Bitcoin ETFs, approved in January 2024, have made pricing and access more familiar to boards. Custody and execution options have matured.
The governance lessons from these cases have not changed:
- Decide the purpose first. Strategy, reserve or tactical position. Each implies different sizing, funding and communication.
- Write down the exit criteria. Tesla's sale was a legitimate decision; clear criteria make such decisions easier to defend. See rebalancing and selling corporate Bitcoin.
- Match funding to risk appetite. Cash funding and debt funding produce very different companies.
- Anticipate stakeholder reaction. Customers, employees and investors may care about Bitcoin for reasons unrelated to price.
- Explain it plainly and consistently. Each of these companies was judged as much on its communication as on its returns.
Companies should take their own accounting, tax and legal advice before following any of these paths.
How The Bitcoin World helps
We help boards learn from these cases and design a Bitcoin approach that fits their own purpose, balance sheet and stakeholders, from policy and board papers through execution planning and custody design. Execution, custody and settlement are carried out by licensed third-party institutions; we do not hold client assets. See our board advisory service.
