Unlike Dorsey, who has said he is purchasing $10,000 a week, Faber hasn't revealed how much he has purchased - could be anything from a hundred dollars to a million dollars. It would be interesting to know, but I doubt he'll reveal it.

More importantly than him buying it himself, according to this article, he has suggested to his followers that they should buy bitcoin with an amount of fiat they can afford to lose. He has quite a large following of his monthly "Gloom, Boom and Doom" newsletter, so his sensible advice will reach many new potentially users.
