Pay attention to the early date of creation of Bitcoin addresses, not the duration of storage.

Are you suggesting that several people agreed to transfer bitcoins 15 years later on the same day?

29/01/2009 - 20/09/2024 - Guinness Book of Records

Accidentally.

A month ago, namely on 09/20/2024, an event occurred that can be entered into the Guinness Book of Records.
From 5 bitcoin addresses, one person transferred 250 BTC (50 from each address).
To date, this has been the longest holding of accounts on blockchain addresses on the Bitcoin network.

These were 5 accounts:
Created 29/01/2009 – 1C4rE41Kox3jZbdJT9yatyh4H2fMxP8qmD
Created 30/01/2009 – 18E5d2wQdAfutcXgziHZR71izLRyjSzGSX
Created 31/01/2009 – 13J8FkimCLQ2EnP1xRm7yHhpaZQa9H4p8E
Created 31/01/2009 – 1MBBJBFEaYKHFZAeV7hQ7DWdu3aZktjzFH
Created 02/02/2009 – 1CGT3Ywaa2upJfWtUtbXonDPNTfZPWqzmA

Let me remind you:
03/01/2009 – Satoshi Nakamoto generated the first Bitcoin block (received 50 BTC).
10/01/2009 – The second to generate a block was the late Hal Finney (received 50 BTC).
12/01/2009 – First transaction, Satoshi transferred 10 BTC to Hal Finney.

Satoshi Nakamoto and Hal Finney were the first to start mining Bitcoin, so there is a very high probability that these accounts were created by Satoshi Nakamoto himself.

It is surprising that few people pay attention to this outstanding event.

For people who do not know how the public blockchain works, I will remind you how easy it is to verify this information. For example, I will show only one address.

What is known about Bitcoin in the Guinness Book of Records?

ChatGPT responds:

Bitcoin has entered the Guinness World Records in several categories. It was recognized as the world's first decentralized cryptocurrency, developed as a solution for financial transactions without the need for intermediaries. This project, started in 2009 by Satoshi Nakamoto, followed earlier unsuccessful attempts to create digital currencies.

Bitcoin also holds the title of the most valuable cryptocurrency, with a market capitalization reaching $816.69 billion in March 2022. Notably, the Guinness World Records mentions events like the first commercial Bitcoin transaction in 2010, when programmer Laszlo Hanyecz purchased two pizzas for 10,000 BTC — now celebrated as Bitcoin Pizza Day.

Additionally, the record book acknowledges El Salvador as the first country to adopt Bitcoin as legal tender in 2021.

Satoshi is alive and even now making transactions on his accounts.

For example 5 accounts:

Created 2009.01.29: 1C4rE41Kox3jZbdJT9yatyh4H2fMxP8qmD
Created 2009.01.30: 18E5d2wQdAfutcXgziHZR71izLRyjSzGSX
Created 2009.01.31: 13J8FkimCLQ2EnP1xRm7yHhpaZQa9H4p8E
Created 2009.01.31: 1MBBJBFEaYKHFZAeV7hQ7DWdu3aZktjzFH
Created 2009.02.02: 1CGT3Ywaa2upJfWtUtbXonDPNTfZPWqzmA

Each account had 50 BTC frozen, which were transferred on 2024.09.20.

Let me remind you:
2009-01-03 - Satoshi Nakamoto generated the first Bitcoin block (received 50 BTC).
2009.01.10 - The second to generate a block was the late Hal Finney (received 50 BTC).
2009-01-12 - First transaction, Satoshi transferred 10 BTC to Hal Finney.

The real Satoshi is Adam Back.
