Some of the oldest mining wallets have awakened. Several early miners from the first stage of Bitcoin mining have moved their 50 BTC block rewards.
In a rare whale event, several long-dormant wallets have started moving their holdings. The coins were a part of the 50 BTC mining reward from the very early days of the Bitcoin network.
While it is not rare to see an old wallet move their coins, this time, as many as five entities have shifted their balances from known addresses.
All the addresses became active in the span of an hour, then moved to new CoinJoin address formats. Each of the transactions 1, 2, 3, 4 and 5 moved exactly 50 BTC minus fees into brand-new wallets.
One of the wallets was last active on 02.02.2009, coinciding with the time when only a few miners produced blocks, together with Bitcoin’s founder, the pseudonymous Satoshi Nakamoto. Three of the addresses were created on January 31, and the oldest is from January 29, 2029.
For the last time, Satoshi era BTC was transferred about nine months ago, ending up in a hot wallet that now sits empty. But the recent transfer is the first series of transactions coming from several different addresses, created at different times. The addresses have not been flagged as wallets belonging to Satoshi Nakamoto, but may be linked to Hal Finey or other very early miners.
