The world of cryptocurrency is often shaped not just by retail traders, but by powerful entities known as Bitcoin whales—investors or institutions holding more than 1,000 BTC. These players can influence market sentiment and price movements with a single transaction. Among the most prominent are Grayscale Bitcoin Trust, the U.S. government, MicroStrategy, and Tesla, led indirectly by Elon Musk.
As market watchers continue to analyze trends in 2025, changes in these giants’ Bitcoin holdings have sparked renewed interest. From legal battles over ETF approvals to government asset sales and corporate treasury strategies, understanding their actions offers valuable insight into the broader adoption and stability of Bitcoin.
Grayscale Bitcoin Trust: 654,885 BTC Held
Grayscale Bitcoin Trust (GBTC), established in 2013 by Barry Silbert—founder and CEO of Digital Currency Group (DCG)—remains the largest publicly identifiable Bitcoin holder. With a staggering 654,885 BTC in custody, valued at over $17 billion, GBTC leads the whale rankings.

The trust operates by allowing investors to exchange cash or Bitcoin for shares backed by actual BTC holdings. This model simplifies exposure for traditional investors who may lack the technical knowledge or regulatory confidence to hold crypto directly. A 2% annual management fee applies, and shares trade on secondary markets like OTCQX.
Since its inception, Grayscale has played a pivotal role in legitimizing Bitcoin as an institutional asset class. However, its long-standing battle with the U.S. Securities and Exchange Commission (SEC) over converting GBTC into a spot Bitcoin ETF has been a major catalyst for market anticipation.
In October 2022, Grayscale filed a lawsuit against the SEC after repeated rejections of its ETF application. With major financial firms like BlackRock, Fidelity, and Invesco also entering the race, the outcome could set a precedent. If approved, a spot ETF would likely unlock massive inflows from pension funds, mutual funds, and other traditional capital sources—potentially triggering a new bull cycle.
U.S. Government: 164,004 BTC in Custody
The U.S. federal government holds 164,004 BTC across two known addresses—making it one of the top Bitcoin whales despite never purchasing any voluntarily. These holdings were acquired through law enforcement seizures tied to criminal activity:
- 69,369 BTC seized from Silk Road in November 2020
- 94,643 BTC recovered from the Bitfinex hack in January 2022
- 51,326 BTC confiscated from James Zhong, a hacker linked to Silk Road thefts, in March 2022
In March 2023, the government sold 9,861 BTC at an average price of $21,877 per coin, generating $215.5 million after fees. While this represented only a small fraction of its total holdings, the sale raised concerns about potential future liquidations.
Market analysts closely monitor government wallets because any large-scale sale could destabilize prices. Given that over 150,000 BTC remain unspent, speculation persists about whether additional auctions will occur—especially as federal agencies explore ways to monetize seized digital assets.

MicroStrategy: 152,333 BTC Accumulated Strategically
MicroStrategy Incorporated, a publicly traded U.S. firm specializing in business intelligence software, has become synonymous with corporate Bitcoin adoption under CEO Michael Saylor’s leadership.
Starting in August 2020, MicroStrategy began allocating capital to Bitcoin as a treasury reserve asset—initially investing $250 million, followed by another $175 million. By July 31, 2023, the company held 152,333 BTC, purchased at an average cost of **$29,672 per coin**, with a total investment of $4.53 billion.
This represents a 17.45% increase from its 129,699 BTC holdings in 2021. Notably, MicroStrategy has maintained a strict "buy-and-hold" strategy since early 2021. The only exception was a tax-loss harvesting move in December 2022 when it sold 704 BTC at an average price of $16,776—locking in losses for tax benefits while retaining the vast majority of its portfolio.
With no plans to sell and ongoing signals of confidence from leadership, MicroStrategy continues to serve as a model for other corporations considering Bitcoin as a long-term store of value.
Tesla: Holding Steady with 10,800 BTC
Tesla’s journey with Bitcoin has been anything but stable—but its current stance reflects strategic restraint.
In February 2021, Tesla announced it had purchased approximately **$1.5 billion worth of Bitcoin**, equivalent to around **41,666 BTC** at an average entry price of $36,000. Shortly after, the company made headlines by accepting Bitcoin as payment for vehicles—a move reversed just months later due to environmental concerns over mining energy consumption.
By Q2 2022, Tesla disclosed it had sold 75% of its holdings, citing “liquidity needs” and ESG (Environmental, Social, and Governance) considerations. The remaining 10,800 BTC have been held without further transactions.
Meanwhile, Tesla’s sister company SpaceX—privately held—also invested in Bitcoin. According to a Wall Street Journal report from August 17, SpaceX sold approximately $373 million worth of Bitcoin between 2021 and 2022. While exact quantities aren’t public, Elon Musk confirmed during a 2021 event that SpaceX owns BTC.
When news of Tesla’s partial exit emerged earlier, Bitcoin’s price dropped over 8%, briefly falling below $25,400—the lowest level since June 20. This reaction underscores how deeply market sentiment is tied to high-profile holders.
Today, Tesla’s unchanged position suggests a wait-and-see approach amid regulatory clarity and sustainability improvements in the crypto space.
