Perhaps because Bitcoin is becoming 'style'. A style that is defined by innovation and (decentralised) trust in each other through hard rules set by transparent code as opposed to an undefined club of men in a dark room. Trust in centralised institutions is remarkeably low among youth. They understand the flaws of current organisation of money and are more than happy to do things in a different way.

This style will continue to find more supporters, putting pressure on existing institutions to do better. Perhaps Bitcoin can even become a stable numeraire against which everything else will be measured.

Once the credibility line has been crossed, it will happen quickly. John McAfee is no fool...
