A one-decade Bitcoin whale that mined BTC in the Bitcoin network’s first month of existence has moved more assets to the cryptocurrency exchange Kraken. The whale, which held $73.4 M Bitcoin, transferred $ 634k worth of BTC to Kraken as a second transaction in about 10 years. 

In an X post, Arkham Intel shared that the whale transferred a more significant amount compared to the first move over a month ago, in which the same account was transferred about 5 BTC to Kraken. The account has now deposited a total of $4.21M to Kraken.

HBO’s documentary sparks Satoshi speculation as dormant Bitcoin whales move to Kraken

This development comes amid renewed speculation over the true identity of BTC’s pseudonymous creator, Satoshi Nakamoto. HBO plans to release the “Money Electric: The Bitcoin Mystery” documentary on Oct. 8, which the producers claim will reveal Nakamoto’s true identity

Deceased American computer scientist Len Sassaman is the odds-on favourite to be named Nakamoto in the HBO documentary. Sassaman was a renowned cypherpunk who committed suicide in July. 3, 2011 — a little over two months after Nakamoto disclosed they had “moved on to other things.”

A memorial of Sassaman was encoded into Block 138,725 of the BTC blockchain.

It’s unclear exactly what connection Sassaman had with Bitcoin. Still, several 13-year-old X posts show Sassaman criticizing BTC for its lack of “privacy” features and “fraud reversal protection.”

In 2021, Sassaman’s late wife, Meredith Patterson, said that to the “best of my knowledge, Len was not Satoshi.” Bitcoin is currently trading at $63,593, a difference of +0.84% in the last 24 hours. 

Blockchain-based betting platform Polymarket shows that Sassaman is the leading candidate, though the implied probability that he is Satoshi has dropped on the site to 24% from as high as 68% on Oct. 3.
