An “ancient” Bitcoin whale that mined BTC during the first two months of the Bitcoin network’s existence has moved more BTC to cryptocurrency exchange Kraken, according to a blockchain data firm.

“This Bitcoin was mined ONE MONTH after Bitcoin’s launch in Feb/March 2009,” Arkham Intelligence noted in an Oct. 4 post on X.

The mysterious Bitcoin whale transferred 10 Bitcoin, worth $610,000, in the latest transfer on Oct. 3. Since Sept. 24, they have moved a total of $3.58 million to Kraken. Before this activity, the wallet address had been dormant for a decade, as mentioned in an earlier post by Arkham:

“After moving several times from 2011-2014, his Bitcoin was then held dormant for almost 10 YEARS straight – during which it increased in value from $474K to over $80M.”

The wallet address “3JZsd…QerUW” currently holds 1,169 Bitcoin, valued at $72.4 million at today’s prices, according to Arkham data.

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

Deceased American computer scientist Len Sassaman is considered a strong candidate to be named Nakamoto in the HBO documentary. Sassaman was a well-known cypherpunk who tragically took his own life on July 3, 2011, shortly after Nakamoto disclosed they had “moved on to other things.”

A memorial for Sassaman was encoded into Block 138,725 of the Bitcoin blockchain. While the exact connection between Sassaman and Bitcoin remains unclear, Cointelegraph discovered several 13-year-old X posts from him criticizing Bitcoin for its lack of “privacy” features and “fraud reversal protection.”

Back in 2021, Sassaman’s late wife, Meredith Patterson, stated, “to the best of my knowledge, Len was not Satoshi.”

Currently, Bitcoin is trading at $61,815, up 1.5% over the last 24 hours but still 16% below its all-time high of $73,738 reached on March 14, according to CoinGecko data.
