What about the "real" currency bubble? Are you not as concerned with the Federal Reserve issuing debt that will not be (cannot possibly be) paid? I would rather invest in BTC now before that one bubble pops, which in my opinion, will.
Do what you will with your hard-earned paper, and let others invest in what they may.
For the 20th time, I'm not trying to tell others to buy or sell, I'm not predicting prices, I'm not trying to convince anyone, scare anyone or influence anyone's decisions. I am simply putting the info out there that every speculative bubble in human history has ended the same. People can take it or leave it.
As far as what I think of the Fed and U.S. gov't debt, that is a whole nother can of worms that I have no interest in getting into. Its way too long of a topic and off topic for this forum as far as I'm concerned.
