In the cryptocurrency universe, the term “whale” refers to individuals or organizations that own large amounts of a specific crypto, exerting direct influence over liquidity and market prices.

It’s as if these “giants of the sea” could change the course of the waters with a simple flick of their tail. When we talk about Bitcoin (BTC), whales can range from governments and investment funds to companies and the anonymous creator of the asset itself.

Below, we list seven of the largest Bitcoin holders in 2025, explaining who they are, why they accumulate so much BTC and how this affects the market, updating the list published in 2024.

1. Satoshi Nakamoto — 1.1 million BTC

The most iconic name is undoubtedly that of Bitcoin creator Satoshi Nakamoto. Little is known about his identity or whereabouts, but it is estimated that he holds around 1.1 million BTC. These coins were mined in the early days, when few believed in Bitcoin's potential and the mining difficulty was very low.

  • Why is it relevant?
    Satoshi’s holdings have remained untouched for over a decade. If for some reason some of these coins were to be moved, it could cause a major stir in the market. The possibility that these BTC will never be spent is what makes many say they are out of circulation.

2. Exchanges — ~850 mil BTC

Among the largest exchanges, Binance stands out for holding more than 550,000 BTC, the result of the sum of deposits from millions of global users. Exchanges like Coinbase also store large amounts of Bitcoin on behalf of their customers. However, this is not the property of the company itself, but rather an amount under custody for thousands of traders and investors.

  • Why is it relevant?
    Large exchanges exert significant influence on BTC liquidity and buying and selling flows. A security move or announcement (or lack thereof) can instantly affect market sentiment. Furthermore, Binance has a huge global reach, including operations in Brazil, which further reinforces its role as a “guardian” of a significant portion of BTC in circulation. Other major exchanges, such asCoinbase, KrakenandOKX, are also among the institutions with the largest BTC reserves, each in the hundreds of thousands of bitcoins.

3. US Government — 213 thousand BTC

Many people don’t know this, but the US government has accumulated a considerable amount of Bitcoin, estimated at over 213,000 BTC. These assets come largely from seizures related to illegal activities, such as Silk Road and other cybersecurity operations.

  • Why is it relevant?
    The government usually holds auctions to sell off some of its confiscated assets, but it keeps a significant balance. If, for political or regulatory reasons, it decided to sell a large amount at once, this could have an impact on the market.

  • And El Salvador?
    Despite being a country that has adopted Bitcoin as legal tender, El Salvador’s BTC reserves are relatively small (~6,000 BTC). This is nowhere near the US stockpile, but the Salvadoran pioneering initiative continues to draw global attention.

4. Chinese government — 190 thousand BTC

China has about 190,000 BTC, much of it from seizures or closures of illegal mining and exchange operations. Despite severe restrictions on cryptocurrency trading in the country, the Chinese government retains these reserves.

  • Why is it relevant?
    Any official movement of this amount could influence the market. Some speculate that China could use this BTC strategically, but so far, there are no concrete signs that it will get rid of the amount or even buy more.

5. BlackRock — 305 mil BTC

BlackRock, one of the largest asset managers on the planet, has also entered the radar of Bitcoin whales by acquiring more than 305,000 BTC over the years. With billions of dollars under management, the company sees Bitcoin as an opportunity for diversification.

  • Why is it relevant?
    The approval of BTC investment products (such as ETFs) and the interest from traditional funds signal a growing institutionalization of the crypto market. Should BlackRock further expand its exposure, it could increase BTC’s legitimacy among conservative investors.

6. MicroStrategy — 226 mil BTC

Under the leadership of Michael Saylor, MicroStrategy has become famous for converting a large portion of its cash into Bitcoin. By 2025, MicroStrategy will have more than 226,000 BTC in its treasury.

  • Why is it relevant?
    Saylor argues that BTC is a hedge against inflation and a reserve asset, encouraging other companies to do the same. This corporate adoption reinforces Bitcoin’s institutional credibility.

  • What about the Winklevos brothers, the Facebook twins?
    Brothers Tyler and Cameron Winklevoss, known for suing Facebook in the past, are Bitcoin investors and have accumulated around 70 thousand BTC. They founded the Gemini exchange and became strong advocates of Bitcoin, helping to popularize it as a store of value and an alternative to the traditional financial market.

7. Fidelity Investments — 181 mil BTC

Another giant in the traditional financial sector is Fidelity, which over the years has expanded its services to include cryptocurrency custody and trading. In 2025, Fidelity will have over 181,000 BTC under management, reinforcing its position as a major financial institution in the cryptocurrency space.

  • Why is it relevant?
    Like BlackRock, Fidelity promotes BTC to a broad base of institutional clients. This adoption by pension funds, insurance companies, and large corporations reinforces the perception that Bitcoin has a place within diversified portfolios.

What does this mean for the future of Bitcoin?

The fact that so many entities — from governments to financial giants — hold large amounts of BTC illustrates Bitcoin’s transition from a “niche” asset to a global store of value, sought after by both private investors and institutions. While its concentration in a few hands can create uncertainty (a massive sell-off could drive prices down), it also indicates that the asset is increasingly seen as a legitimate form of investment or protection.

For the average investor, watching the movements of these whales and large holders becomes a way to track potential trends. A sizable purchase by one of these institutions could signal renewed confidence in BTC, while a large sale or an auction of seized BTC by a government could trigger rapid price drops.

In any case, in 2025, Bitcoin will remain the most relevant digital asset on the planet. And, by all indications, the trend is for more players — whether countries or Wall Street giants — to enter this dispute to see who has the most BTC.

For those who follow the market, the lesson is clear: staying informed about the movements of these important holders can make all the difference when deciding whether to buy, sell or just hold your coins.
