- Coinbase confirmed that it is one of the managers of the strategy, while Blockchain Analytics company Arkham claims to have traced 70,000 BTC to Fidelity.
- SEC archives reveal that strategy only uses NYDFS-regulated custodes, reducing the list to 9 possible companies, including Bitgo, Gemini and Nydig.
Bitcoin Treasury Giant strategy has always been cautious about mentioning his BTC managers. But people outside the company know who they are.
To begin with, Strategy has repeatedly cited his “different guardianship schemes” – there is no exclusive custodian who holds on behalf of the company for the company for the company. A spokesperson for Coinbase confirmed that it is one of the managers of the strategy when requested by Decrypt– But emphasized that MSTRA Coinbase previously mentioned as one of his managers.
Strategy did not immediately respond to a request for comments from Decrypt About her decision to keep the names of his preservators.
The issue of the Bitcoin interests of Strategy, and which exactly holds the keys to the stock of $ 72 billion, was recently put forward after controversial statements from the founder of the company, Michael Saylor. In May, Saylor said that it was a “bad idea” to share “proof of reserves” publicly or otherwise offer a detailed list of preservators who quoted security problems.
Our institutional team crushes it – two great statistics of our QBR this week:
1) 8 of the top 10 listed companies with BTC on their balance are Coinbase Prime.
2) There is $ 140 billion crypto in American ETFs, and 81% are stored with Coinbase. We follow> 50 …
– Brian Armstrong (@brian_armstrong) June 27, 2025
Skeptical cryptomarket observers, many of whom have the infection-inducing flow-ups of FTX, Three Arrows Capital, Celsius and others, Saylor criticized the moment he refused to share these details, although others supported the preliminary approach to operational safety. The issue was again in public discourse two weeks ago when Coinbase CEO Brian Armstrong proudly proud of X Pende on X that his company Bitcoin guarded eight of the 10 listed BTC holders – who, in the context of Coinbase, implies one of the strategy of the strategy.
Armstrong’s tweet, however, may not have been as controversial as some initially interpreted. According to Coinbase, Saylor had previously mentioned Coinbase as one of the preservators. Strategy – Formerly MicroStrategy – is a public company that is traded under the Ticker MSTR, so a number of disclosure is expected.
Strategy indeed revealed details about its preservators to the SEC in a letter of April 2023. On 5 April 2023, the supervisor wrote to the strategy to ask how “recent bankruptcies in the crypto industry and failures of certain financial institutions, and the power supply of such events, have influenced your company or have influence on your company.”
At the time, the industry of the collapse of $ 8 billion from FTX staggered. Subscribe Silvergate Bank and Signature Bank were forced to settle their activities in March. During the entire period, regulators and shareholders were wondered whether the BTC of the strategy was still safe – in particular because strategy had used part of his BTC as collateral for a loan from Silvergate.
But when the strategy answered two weeks later and answered the SEC request to “tell us the names of your managers,” the company SEC rule 83 called to keep the details confidential.
What was publicly left public is that strategy keeps his bitcoin to accounts in “established, institutional preservators who have demonstrated data on compliance with regulations and information security, and all our managers are New York Department of Financial Services (” NYDFS “) regulated preservators.”
That is descriptive enough to resolve the list of probable preservators.
Of the 35 recipients of NYDFS Bitlicenzen, only 9 limited target confidence Charters when strategy sent his letter in the spring of 2023. They include bitgo, coinbase, gmo-z.com, fidelity, bakkt, gemini, nydig, paxos and standard custody & trust company.
Coinbase is not a big surprise, especially since the exchange is often cited in MSTR archives such as its “main market for bitcoin”. Strategy even made his very first bitcoin buy through Coinbase.
In the meantime, Blockchain Analytics platform Arkham Intelligence Platform claims that he traced 70,000 of the company’s BTC in May to Fidelity.
The company has not confirmed that it has a part of its BTC with Fidelity, but the company fits in the profile because it is on the list. A source that is familiar with Fidelity Digital Asset Services Business Decrypt The company takes the security of its customers very seriously and would not show the information from customers – directly or indirectly.
There are also a few among the radar companies on the list of possibilities.
GMO-Z.com is the American subsidiary of GMO Internet Group, a large Japanese internet conglomerate that owns ONAAME domain registration, web hosting, payments and a crypto exchange and mining company. It is also the issue of Gyen, who calls it the first regulated Japanese yen stablecoin, and sister, an American dollar stabilecoin.
It is unlikely that GMO-Z has one of the strategy Bitcoin Because the company explicitly says that it will keep reserves in Gyen or Zusd, his American dollar-pegged Stablecoin.
The Standard Custody & Trust Company, which Ripple took over in June 2024, was a subsidiary of Polysign. Polysign was partly founded by Ripple Fellow founder Arthur Britto, Ripple Chief Technology Officer David Schwartz and is led by CEO Jack McDonald. McDonald is also the SVP from Stablecoin in Ripple.
Standard guardianship has gone out of the way to fly under the radar and position itself as an institutional figure, white-label custodian.
Bakkt Trust Company is also on the list. Former parent company Bakkt has been many things over the years. In 2019, Bakkt Digital Asset Custody Company took over and a limited purposes Trust Charter landed it was one of the first companies to become a Bitcoin keeper regulated by NYDFS.
But the company has sold its guardianship company to its parent company. Neither Bakkt nor intercontinental exchange responded to a request from Decrypt about whether the guardianship company still has customers.
