I have had to sit tight on my PM supply and wait it out for a year now and then while things consolidate.  Thankfully I have had zero difficulty doing so and ignoring all of the people calling a top.  Maybe this will be the time that the PM "bubble" finally pops, but I can think of no plausible change in the mechanisms which have been responsible for the increased value over the last decade.  There are things about PM's which concern me quite a lot and caused me to diversify, but a popping bubble is not really one of them.

I project that Bitcoin will either increase in value by several (if not many) orders of magnitude, or it will go to zero.  I think that the latter is much more likely than the former and always have, but I do hold enough BTC as a long-shot bet that if it takes hold I'll do much better than I possibly could with PM's.
