PMs look cool where as bitcoin doesn't look anything . I doubt bitcoin will actually become anything in the real world, it's more of a fad for computer peoples.
Precious metals win on every level especially the most important: Trust. Security. History. Awesomeness (depending on the coin or medal of course). .
I feel all the money has been made with bitcoin, far more risk with it compared to metals at current prices. Made some people incredibly rich, but I can't see it being allowed to going anywhere from here (but admittedly I have said that before and look where it is now).
