TLDR:
- Analysis of 2009 email records that contrast with the documented physical activity of Hal Finney.
- Chronological coincidence between the cessation of Satoshi’s communications in April 2011 and the passing of Len Sassaman months later.
- Current valuation of $87.8 billion for the 1.1 million BTC stored in the original wallets.
Analyst Fred Krueger has presented a hypothesis linking the identity of Satoshi Nakamoto to a working team integrated by cryptographers Hal Finney and Len Sassaman. Krueger stated that this collaboration would explain the apparent contradictions between the Bitcoin creator’s activity schedules and the technical capabilities required for the development of the protocol.
After looking at the timeline, the Hal Finney + Len Sassaman duo hypothesis is the most logically sound theory we have.
Here’s why:
1/ The Physical Impossibility: We know Satoshi was emailing Mike Hearn while Hal Finney was running a 10-mile race in 2009. Hal couldn’t be in…

Temporal evidence and technical profiles
One of the pillars of this theory is based on Hal Finney’s alibi during 2009. Krueger points out that, according to analyzed correspondence records, the pseudonym Satoshi Nakamoto sent emails to Mike Hearn at the exact moments when Finney was participating in a 10-mile race. Under this premise, Finney’s physical impossibility to perform both tasks simultaneously suggests the involvement of a second person.
Regarding the division of roles, Krueger’s analysis proposes that Finney would have been responsible for the engineering and C++ code. On the other hand, Len Sassaman, an academic-level cryptography expert, would have contributed the writing of the White Paper. Documentation provided by Krueger highlights that Sassaman resided in Belgium, which could justify the use of British idioms and the academic style present in the original Bitcoin texts.
The end of communication and the fate of the funds
The theory takes on a more complex nuance when analyzing the end of the Satoshi era. The creator’s last public message occurred on April 26, 2011. Background information confirms that Len Sassaman took his own life 68 days after that date. In the same period, Hal Finney was already facing the advanced stages of Amyotrophic Lateral Sclerosis (ALS), which drastically reduced his ability to write or program.
Krueger suggests that Satoshi’s disappearance was not an act of mystical will, but an inevitable consequence of personal tragedy. For the analyst, the paralysis of one and the death of the other sealed the fate of the private keys. At the time of these events, the value of the 1.1 million BTC was approximately $800,000, a significantly lower figure than today.
According to Krueger’s projections, this scenario implies that Satoshi’s bitcoin reserve must be considered as “burned” supply. Since there is no access to the keys, the assets would remain permanently locked on the blockchain. This, according to the expert’s analysis, eliminates the market risk that a massive sale by the founder would pose, given that the probability of those coins moving is reduced to zero under this theory.
The validity of this hypothesis continues to be a subject of study within the crypto community, while the market closely watches any movement in the old wallets dating back to the “Satoshi era.”
