Around 250 BTC from the early days of Bitcoin, known as the “Satoshi era,” were transferred on Friday in five separate transactions, each moving around 50 BTC to new wallets. The total value of the transfers was close to $16 million.

JUST IN: Satoshi era #Bitcoin wallets just moved over 250 BTC worth $16 million mined in Jan 2009 🤯

The owner of the wallets hodled from $0 to $63,000. Legend! 🙌

The coins were originally mined in January 2009, just months after Bitcoin’s launch, and have lain dormant since. Arkham blockchain analysis shows the wallets are not linked to Bitcoin’s pseudonymous creator, Satoshi Nakamoto.

The original wallets that moved the coins are: 1CGT3Ywaa2upJfWtUtbXonDPNTfZPWqzmA, 1MBBJBFEaYKHFZAeV7hQ7DWdu3aZktjzFH, 13J8FkimCLQ2EnP1xRm7yHhpaZQa9H4p8E, 18E5d2wQdAfutcXgziHZR71izLRyjSzGSX, 1C4rE41Kox3jZbdJT9yatyh4H2fMxP8qmD

The transfers likely belonged to an early Bitcoin miner who acquired the coins when BTC was practically worthless. After holding them for over 15 years, they are now valued at $16 million.

This demonstrates the conviction of early believers who recognized Bitcoin’s potential value long before the recent meteoric price rises. The anonymous owner mined and held these coins when Bitcoin was a niche experiment, exhibiting remarkable faith.

While the original owner remains a mystery, the transfers are among one of the largest amounts of “Satoshi era” Bitcoin ever moved. There has been no activity sending the coins to exchanges, indicating the owner may intend to continue holding them.

The Bitcoin mining difficulty reached a new all-time high of 92.67 trillion on September 11. This represents a 3.04% increase over the last 24 hours and continues an upward trajectory in mining competition.

The Bitcoin difficulty chart plots the historical increases and decreases in mining difficulty over time. It measures how hard it is for miners to find a valid hash for the next block. Higher difficulty requires more computing power to mine new Bitcoin.

When combined with the Bitcoin price, difficulty helps determine miners’ profitability and return on investment. The metric soared in 2024 amid massive growth in Bitcoin’s overall hash rate and adoption.

The rising difficulty shows intensifying competition on the Bitcoin network as more miners fight for limited block rewards. This is generally constructive for network security and decentralization.

Despite rough market conditions this year, the difficulty increase displays the unprecedented demand for Bitcoin block rewards. It underlines the incredible security offered by the collective computing power of miners around the world.

The difficulty adjustment algorithm built into Bitcoin’s code dictates the pace of change in mining competition. It is programmed to find blocks approximately every 10 minutes, maintaining a steady influx of new Bitcoin over time.

This predictable Bitcoin issuance schedule makes its inflation rate easy to model and appeals to investors compared to fiat currencies subject to central bank policies.

Tokyo Electric Power Company (TEPCO), Japan’s largest electricity provider, has begun mining Bitcoin through its subsidiary Agile Energy X using excess renewable energy that would otherwise be wasted, as per reports from Asahi.

With over 27 million residential and business customers, TEPCO established Agile Energy in 2022, and now they are exploring Bitcoin mining powered by surplus renewable energy. The subsidiary has installed mining rigs next to solar farms in Japan’s Gunma and Tochigi prefectures.

The initiative helps reduce wasted green energy from solar and wind farms that are forced to curtail production to avoid overloading Japan’s grid. This energy is now being diverted to generate Bitcoin.

“Green energy producers have to operate their businesses on the assumption that part of the power they generate is wasted,” said Agile Energy President Kenji Tateiwa. “If bitcoins were to provide a new source of income for similar power producers, who are being exposed to overinvestments, that would prompt more green energy to be introduced.”

The project shows how Bitcoin mining can incentivize renewable energy growth by providing producers with additional revenue streams. Tateiwa said Bitcoin profits could encourage further investment in clean energy to power the mining.

Other countries are also tapping excess renewables for Bitcoin mining, like El Salvador, which uses its geothermal energy. This dispels the myth that Bitcoin is environmentally hazardous, as much mining uses energy that would otherwise be wasted. 

More and more companies and countries are figuring out how to turn waste and surplus energy into the hardest money on earth. As more renewables come online, Bitcoin mining will help reduce wasted power and emissions.
