The wallet, which has been completely inactive since the ICO, on Saturday transferred all of its 8,000 ETH to another newly created address, on-chain data from Etherscan shows.
The fund movement was made in two transactions, with one test transaction worth just 1 ETH first, followed by another transfer of the remaining 7,999 ETH.
In total, the transfers are worth some $15.2 million by today’s exchange rate, representing a massive increase in the value of the wallet since it was set up during the ICO with ETH worth only $2,500.
One noteworthy detail is that the new wallet that the funds were sent to recorded a separate inbound transaction of 207 ETH, worth close to $400,000, just moments earlier.
That transaction came from a wallet that have been dormant since 2017, and it remains unknown who owns it and why the funds are now being consolidated.
On Twitter, on-chain researcher Lookonchain was quick to share details about the original transaction, with members of the crypto community taking the opportunity to comment under the tweet with their own theories about the transfer.
Ledger launched its first version of a hardware wallet in 2014, which makes it plausible that the mysterious Ethereum whale could be storing his or her funds on one of the early iterations of the device.
