Why do you feel compelled to spend so much time on a forum dedicated to Bitcoin if you aren't interested in how you can use it to your advantage?
He writes articles about Bitcoin, including paid ones. Being here makes him and others think he is specialized in Bitcoin, or something like that
(1) I am a prof of computer science and I am supposed to understand computer things. (2) I am really bothered by people "selling" bitcoin to ordinary folk as an hedge against inflation, fantastic investment, etc.. I view such marketing as a scam, and I consider to be within the obligations of my job to alert the public (who pays my salary) against that scam. (Fortunately, that marketing does not seem to have had much result yet, and seems to have become more discrete.)
I do not write paid articles. On the other hand, most of what one finds in the net and other media about bitcoin, if it is not just press releases, is written by bitcoin owners, who have an obvious vested interest in pushing bitcoin.
So on which forums are you relentlessly warning people off "investing" in Brazilian Reals? As far as I can tell they are bigger and worse "scam" than bitcoin, by your own logic.
