Thank you both, I thought that he sent them for money. So basically Satoshi didn't sell a single bitcoin that period. I wonder if he believed that by hodling them he would become rich. If that's so, he would be the first hodler.

Now something else that I'm concern about is how he paid for the domain name. Even on anonymousspeech.com, you had to make a payment somehow, cryptocurrency did not exist those days. How he paid for bitcoin.org?
