The legend ex world chess champion Garry Kasparov is the first one people that challenge the technology. In 1996 he played with the super computer Deep Blue (i can write an article about this) and finaly lost. So we can say thst that love the challenges of technology.  Before some years told that he is suspicious about bitcoins but NOW told that was wrong and because everything are maths and calculations is very safe and good for invest. He is very safe that will stop the publishing bitcoin at the magic number 21 and there is any government to print more money. So guys the cryptocoins are more trusted than paper money
