A bullish call on Bitcoin, gold and silver, built on the view that the dollar is losing value fast — good for people who already own scarce assets, bad for anyone holding cash.

• Bitcoin could reach half a million dollars a coin in four to five years.
• Gold and silver are expected to climb sharply too, for the same reason.
• The core argument is a weakening dollar that buys less each year.
• The dollar is seen losing value faster over the next five years than it has over the past fifteen.
• The pitch to savers: move hard-earned money into assets that can't be printed.

Outlook: Expect continued big swings in Bitcoin, with the bull case resting entirely on the dollar keeping up its slide.
