I have a friend who works at adsense in 2009, he said he was paid using bitcoin, several times he received until he later moved to work, he did not use that bitcoin. Now he was surprised, since he was just out back of bitcoin, it costs 1 BTC = US $ 770. Pity of him, even he does not know what that "wallet". That is the story that I heard from him.

I can imagine that he has 500 BTC only, and today he can access back to his wallet, how rich he is!
