Could you please elobrate what you're talking exactly. Did you mean Satoshi to have more number of bitcoins for himself and then selling them for real cash to become rich man ? If it is so, I'm sorry I come to a conclusion that you do not know how bitcoin ecosystem is working.

I'm sure one day or other, Mr. Satoshi will become richest man of this world when bitcoin values will be hitting more than million dollars. I believe this is the only way for Mr. Satoshi to become richer than Bill Gates.
