I am not claiming you are wrong by asking, I am genuinely curious, how do you know?

  People have analyzed the blockchain. Here is a paper that discusses an only somewhat out of date analysis: http://cseweb.ucsd.edu/~smeiklejohn/files/imc13.pdf http://cseweb.ucsd.edu/~smeiklejohn/files/imc13.pdf So in April of this year, 64% of bitcoin had never traded hands and there were about 4 million bitcoins circulating. I also think it is fairly likely that there are people monitoring the 'Satoshi addresses'.
