I believe Satoshi is Hal Finney. The 2 damning reasons are

1) Dorian Satoshi Nakomoto (someone Newsweek claimed was Satoshi incorrectly) lived very close to Hal. I believe Hal either knew of him or saw his name somewhere.

2) Satoshi disappeared at the same time when Hal’s ALS made him unable to work anymore. Hal’s death and Satoshi’s silence are at the same time.

Plus Hal was the first person to communicate with Satoshi publicly. All signs point to Hal and only a dead man could keep a secret like this for so long. RIP
