I'm quite curious tho, what is Satoshi Nakamoto gonna do with all the Bitcoin that he has mined during its early time?

Seriously? He will choose to do with the stash what he choose to do because they're rightly his|her. To me, that's the reward for the good work done by this persons who put upon themselves the new errand of digital currency.
To me something always lead to another, possibly Satoshi Nakamoto thought much about the cashless policy which they worked together to achieved and is commendable and also many information are available on wiki and Google.
