A goth t-shirt of the loser's choosing, depending on whether the Fed would raise rates prior to 2016. I took the "no" position because the Fed strikes me as an overly-cautious supplicant of Wall St, but it was a (symbolic) hedge. Mk and I largely concur on markets and investment. Bitcoin reflects a paradigm shift in finance and economics. As such, it's a speculative play well outside the comfort zone of conventional investment. I have exposed myself to enough opinion and expert testimony that I find the case for BTC compelling; however, hostile movements against it at the legislative level could change things. Bitcoin is like gold in that there isn't enough of it to go around but unlike gold in that it has virtually unlimited utility. That alone makes it interesting to watch. It also gyrates magnificently and suspiciously. My retirement fund isn't in BTC, but I have earnest money there.
