Satoshi Nakamoto Wallet Address: How Much BTC Does Satoshi Have?

The most famous Satoshi Nakamoto wallet address is “1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa”, which is the address Satoshi used to receive the 50 BTC reward from mining the first block on the Bitcoin blockchain. This block is also known as the “genesis block”.

The story of Bitcoin inventor Satoshi Nakamoto is one of the most fascinating mysteries of the last few decades. Even though Satoshi invented a technology that has had a big impact on the world and mined billions of dollars worth of Bitcoin, he has stayed completely anonymous and has left his riches untouched.

The reason why we can tell that Satoshi hasn’t been spending his Bitcoin is that researchers have been able to identify wallets that most likely belonged to him. In this article, we’ll explore the most interesting facts about Satoshi Nakamoto’s wallets and the addresses he used.

Key highlights:

• Satoshi Nakamoto has a huge number of different wallet addresses, more than 20,000 by some estimates.
• Most of Satoshi’s wallets contain 50 BTC, as that was the Bitcoin block reward before the first Bitcoin halving.
• Estimates place the size of Satoshi Nakamoto’s holdings at between 600,000 BTC and 1.1 million BTC (worth $43 billion to $80 billion at current market rates)
• The vast majority of Satoshi Nakamoto’s wallets received a 50 BTC block reward and have remained dormant since.

Satoshi Nakamoto’s wallets

Satoshi used a huge number of addresses, with some estimates suggesting he could have more than 20,000 different addresses. He used a different address to receive each block reward, and since he was the most prominent miner in the early days of Bitcoin, he received a large number of block rewards.

The following table contains examples of Bitcoin addresses that are extremely likely to belong to Satoshi. As you can see, there’s nothing too remarkable about these addresses. The vast majority of Satoshi’s wallets hold 50 BTC, as he wasn’t spending his Bitcoin (except for the transaction to Hal Finney).

Some of these addresses, especially the genesis address, hold more than the 50 BTC mining reward as some Bitcoin users occasionally send BTC to addresses belonging to Satoshi as a tribute.

The “Hal Finney” address

One of the most interesting addresses controlled by Satoshi is the address he used to send 10 BTC to Hal Finney. This was the first Bitcoin transaction between two users, as all the previous transactions were just miners (mostly Satoshi) receiving block rewards from the Bitcoin protocol.

This address currently has a Bitcoin balance of 18.44 BTC, which translates to around $1.34 million at the time of writing. The balance of this address has slowly been growing over time, as it occasionally receives BTC transactions, most likely from people paying tribute to Satoshi for his groundbreaking invention.

The last time this Bitcoin address sent an outgoing transaction was on January 12, 2009, just three days after Bitcoin went live.

Hal Finney was an American software engineer and cryptography activist that was one of the earliest, if not the earliest, adopter of Bitcoin. Below, you can see a tweet about Bitcoin that Hal Finney published on January 11, only about two days after the Bitcoin software was first published by Satoshi Nakamoto.

The fact that Hal Finney was involved with Bitcoin so early has caused some to speculate that he is the person behind the Satoshi Nakamoto pseudonym, but this theory doesn’t have much credence in the crypto community anymore.

The Bitcoin genesis address

The most famous of Satoshi’s addresses is the Bitcoin genesis address. This is the address that mined the first block on the Bitcoin blockchain. The wallet balance of this Satoshi Nakamoto’s address is 100.15 BTC, which is worth about $6.3 million at current prices. Just like the address we mentioned previously, the genesis address occasionally receives BTC as a tribute from users. On January 5, 2024, the address received a massive inflow of 26.9 BTC from an anonymous sender.

A curious fact about the genesis address is that the 50 BTC it received as the reward for mining the genesis block is not spendable. According to an explanation provided by Charles Hoskinson, this BTC is not spendable because Satoshi did not add the genesis block’s coinbase transaction to the global transaction database which is used by Bitcoin nodes. Hoskinson added that he was unsure if this was a deliberate move by Satoshi or just a mistake.

However, the rest of the BTC in addresses controlled by Satoshi Nakamoto is spendable normally. So far, Satoshi hasn’t been spending any of his Bitcoin, which is one of the reasons why many people speculate that he might be dead.

Satoshi owns a huge number of Bitcoin

Since Satoshi wanted to stay private, it’s impossible to confirm with 100 percent certainty that the addresses that are believed to belong to Satoshi Nakamoto actually belong to him. However, blockchain researchers have devoted quite a bit of effort and time to figuring out addresses that most likely belong to Satoshi.

For example, researcher Sergio Damian Lerner estimates that Satoshi Nakamoto mined approximately 1.1 million BTC. Lerner came to this estimate by identifying a pattern in the way Bitcoin blocks were being mined in the era when Satoshi was active. This “Patoshi” pattern allowed him to differentiate between blocks likely mined by Satoshi and blocks likely mined by others with a high degree of confidence.

While it’s commonly accepted that Satoshi Nakamoto most likely mined a huge amount of Bitcoin, estimates vary depending on the source. For example, BitMEX Research said in 2018 that an estimate of between 600,000 and 700,000 BTC is more likely to be accurate than Lerner’s 1.1 million BTC estimate. Even if we use BitMEX Research’s more conservative 600,000 BTC estimate, Satoshi still owns $43.6 billion worth of Bitcoin.

Most likely, many sophisticated traders in the crypto market monitor addresses that are likely to belong to Satoshi Nakamoto. If Satoshi were to suddenly activate one or more of his dormant wallets, that would likely be a massive event in the crypto markets.

There have already been some occasions when Satoshi-era Bitcoin was being moved, but these transactions didn’t come from addresses that are believed to belong to Satoshi.

The $1.2 million transaction to Satoshi’s genesis address

In January of 2024, an unknown user sent 26.9 BTC, valued at about $1.2 million at the time of the transaction, to the address Satoshi used to receive the first-ever Bitcoin block reward. This transaction brought the holdings of the genesis address to almost 100 BTC.

The funds were sent to Satoshi’s address shortly after they were withdrawn from the Binance cryptocurrency exchange. Before sending the transaction to Satoshi, the address had not been used for anything else other than a single BTC withdrawal from Binance. After the transaction, the wallet interacted with a wallet tagged by Arkham Intelligence as belonging to the Robinhood trading platform.

While the reason for the transaction is unknown, some members of the crypto community have speculated that it was a marketing stunt to promote the launch of the first spot Bitcoin ETFs. In any case, the 26.9 BTC sent to the genesis wallet can most likely be considered as permanently removed from circulation.

The bottom line – Satoshi Nakamoto has thousands of Bitcoin addresses

Regardless of whichever estimate we’re using, it’s pretty clear that Satoshi Nakamoto has thousands of different Bitcoin wallets.

Most of his wallets are not too remarkable, as they were simply used to receive a block reward and have been dormant ever since. Still, if we ever see transactions from wallets that are thought to belong to Satoshi, we could see some chaos in the Bitcoin markets.

FAQs

What is Satoshi’s Bitcoin wallet?

Satoshi has more than one wallet — in fact, he most likely has thousands of different wallets. The reason for this is that Satoshi used a new BTC address to receive the reward for each block he mined. The most notable wallets that we know belong to Satoshi are the Bitcoin genesis wallet and the wallet he used to send 10 BTC to early Bitcoin adopted Hal Finney.

How many addresses does Satoshi Nakamoto have?

Satoshi has thousands of different Bitcoin wallets, with some estimates saying that he has more than 20,000 different wallets. Satoshi used a new wallet to receive a reward for every block he mined, which is why he has so many different wallets.

Why do so many of Satoshi’s wallets have 50 BTC?

When Satoshi Nakamoto was mining Bitcoin, the Bitcoin block reward was 50 BTC (after four Bitcoin halvings, the reward is currently 3.125 BTC). Satoshi used a different wallet address to receive each block reward, which is why so many of his wallets have exactly 50 BTC.

Why do people still send BTC to Satoshi?

People still send BTC to Satoshi Nakamoto’s addresses as a way to pay tribute to the inventor of Bitcoin. Sending BTC to a famous address such as the genesis address can also be seen as a publicity stunt, as any activity associated with these addresses gets attention.

Of course, there is also a very slim chance that Satoshi himself is sending BTC to his own wallets. However, this is very unlikely, as none of the wallets identified as belonging to Satoshi have sent any Bitcoin in a very long time, suggesting Satoshi is either dead or simply doesn’t want to touch his wallets, whatever the reason may be.
