Crypto exchange Coinbase currently holds over $25 billion in bitcoin, establishing itself as the world’s largest bitcoin custody entity, with nearly 5% of all bitcoin in circulation.

Coinbase’s holdings are roughly equivalent to the stash held by Satoshi Nakamoto, the enigmatic individual or group credited with creating bitcoin and authoring the original white paper in 2008, according to Arkham Intelligence.

The identified sum was spread across 36 million deposit and holding addresses used by Coinbasein, Arkham reported in a Saturday post on X. The largest cold wallet identified held about 10,000 bitcoin.

But the blockchain analytics company suggested that the exchange probably holds thousands more bitcoins that have not been categorized yet, based on latest financial data from Coinbase. Ongoing analysis will aim to uncover these additional addresses.

Coinbase’s custody of ether (ETH) is significantly smaller when compared to its bitcoin holdings. As per Arkham’s data, the exchange held about $2.6 billion in ether.

The fact that Coinbase may hold as much bitcoin (BTC) as Nakamoto is notable because it is widely believed that the mysterious bitcoin creator mined an impressive amount of bitcoin, with estimates ranging from 600,000 BTC (equivalent to $13 billion) to as much as 1.1 million BTC ($23.8 billion) during the cryptoasset’s early years. 

Tracking the whereabouts of all these bitcoins is considered somewhat challenging due to their dispersion across numerous addresses.

Should the upper estimate prove accurate, Nakamoto would find themselves among the top 50 billionaires globally, closely trailing Chanel chairman Alain Wertheimer.

The identity of the Bitcoin creator has remained unverified, although one public profile which claimed association with Nakamoto indicated a location in Japan.

In Nakamoto’s writings, they variously used both American and British English spellings, as well as idiomatic expressions. This has led some to question whether the inventor’s claimed Japanese identity is accurate.

There have also been observations regarding the timestamps on Nakamoto’s comments, which have led some to speculate that they might not have been located in Japan while working on Bitcoin.

Built on Solana, Loopscale is an orderbook-based lending protocol that pairs the efficiency of direct market matching with the flexibility and UX of modular protocols. We believe Loopscale can help scale NNAs in Solana DeFi and act as their foundational credit layer. Stablecoin deposits and select USD-pegged Loops on Loopscale are offering competitive yields, with an additional upside from farming the protocol and adjacent ecosystem projects (e.g., OnRe, Hylo) for potential future airdrops.
