A move into an inactive bitcoin address since 2009 has raised the possibility that the transfer author is none other than bitcoin creator, Satoshi Nakamoto. The address collected 50 BTCs from a mining reward and is its first activity since February 2009 – just a month after the creation of the bitcoin. As of today, 50 BTCs are equivalent to approximately US$ 500,000.

According to data published by Cointelegraph, the address 17XiVVooLcdCUCMf9s4t4jTExacxwFS5uh has moved its entire mining reward from 50 BTC to two different wallets. 40 BTCs are inactive at what appears to be a change address. The remaining 10 BTC were sent to a multisig address – which requires multiple approvals to be moved.

But after all, it was Satoshi Nakamoto who moved the wallet? It is known in the community that Satoshi’s “fortune” is spread among several wallets, each containing a “coinbase” transaction. There were only three people who knew about the bitcoin at the time: Satoshi, Hal Finney, who had since died, and Martti Malmi

Theories about the possible owner of these resources include the wives of Finney and Malmi, but Satoshi is also a likely candidate. The complex chain of transactions suggests that the owner of the wallet is seeking to hide the destination of the resources. It is also theoretically possible, but unlikely, that an external actor uses brute force to gain access to the private key of this wallet.
