Bitcoin = Bubble Coin?
In his podcast (ep. 247, 12:56 - 21:20) Peter Schiff warns about the possibity of crypto currency bubble by, among others, comparing their price surge to the one of internet stocks in 1999/ 2000.
You can agree with him or not. However, it was Schiff, who was warning in 2005 - 2006 about the upcomming economic crisis. Back then everybody laughed about him. Well, the rest is history.
