David Kleiman, who unfortunately passed away in 2013, could be our best candidate for Satoshi Nakamoto's true identity. Here's an article on Kleiman's background and story. None of those claiming to be Satoshi have ever moved the genesis blocks Satoshi is known to own the private keys to. With Satoshi holding 1 million plus btc, which are now worth more than $4 billion, the best explanation is Satoshi must have passed away.

No.
Even Mike clues everyone in as to what happened to all the early coins that are still unspent.
I no longer have the keys that were referenced in my initial emails with Satoshi. That's why the remaining coins are unspent. At the time bitcoins had no value at all and nobody else was using the system, so I didn't bother backing up the wallet and eventually lost it. Back then there were no forums, no markets, no exchanges, no usage at all as far as I could see and Satoshi did not seem to have any interesting in marketing either.

Aside: Re the last link above, I smell an update for the below in the making ...
Oh, and speaking of "no market", let's revisit Mike's first post, eh?
