In the media: the German government and Mt. Gox
In recent months, there has been a lot of talk about the German government, Mt. Gox, and the sale of their bitcoin holdings.
The Federal Criminal Police Office (BKA) sold around 50'000 bitcoins in July 2024; the bitcoins were owned by the federal state of Saxony, which received them in the case of the arrest of the operator of the online streaming platform Movie2k. The state of Saxony is estimated to have made more than $2.9 billion from the sale of these bitcoins.
Also in July, the trustee of Mt. Gox announced that the company had begun repayments to creditors as part of the 2014 bankruptcy, repaying around 140'000 bitcoins ($8.96 billion at current prices) to affected customers.
Both events have led to considerable selling pressure on the Bitcoin market and many market participants have wondered which other countries, institutions, companies and private individuals still hold considerable amounts of bitcoin and could sell them, thus creating further selling pressure in the future.
Who owns the most bitcoins?
Not surprisingly, the largest Bitcoin holders are mainly exchanges and financial institutions that hold Bitcoin on behalf of their clients. Thus, the largest bitcoin holders, in order from first to fifth place, are Coinbase (≈850'000 BTC), followed by Binance (≈660'000 BTC), BlackRock (≈347'000 BTC), Fidelity Custody (≈289'000 BTC), and Grayscale (≈264'000 BTC). To put this into perspective, Coinbase holds around 5.4 percent of all BTC in free circulation, with a current total value of USD $54.4 billion. These are not the largest addresses per se, as some of these entities hold their bitcoins on multiple addresses. So far, so good, no big surprise, right?
Now let's take a look at the slightly more special “bitcoin whales”: In sixth place is MicroStrategy with ≈226'000 BTC, in seventh place is the US government with ≈203'000 BTC, in twelfth place is a Mt. Gox hacker with ≈79'000 BTC, and in 15th place is the first address that could not (yet) be assigned to anyone, it contains ≈78'000 BTC.
"Not your keys, not your coins…", right?
Despite the widespread credo “Not your keys, not your coins”, it is plausible that many exchanges and institutions, such as BlackRock and Fidelity, are among the largest holders of bitcoin. Many bitcoin owners do not yet seem to be in a position to be their own bank or simply have no interest in ever doing so. This is not too worrying, although the centralization of bitcoin holdings carries a certain risk and fundamentally contradicts Satoshi Nakamoto's original vision and idea, but this is a topic for another time...
Which companies own bitcoin?
How about companies? Which companies own the most bitcoin? As we already know, MicroStrategy, Michael Saylor's company, is at the top of the throne, for now. What does it look like below?
