For what it's worth, I recall Jim Rogers recently said he expects things to start unraveling after summer, or if not then after fall. He's finally buying gold again. He seems to have been right about just about everything, including gold's correction.
My own guess is that BTC will continue sliding down over the next few weeks/months, perhaps to $50 if things get dire enough (very bad news could push it even lower of course), but that the global economy is sitting on a powder keg. Japan especially, but also Europe and the US. The next crisis could come at any time, and when it does Bitcoin (and gold) could skyrocket. Note that depending on the type of crisis the opposite might happen first, temporarily (remember 2008).
Despite my short-term bearishness, I wouldn't be tempted to sell core positions in either asset; there's too much pent up steam to get cute with trading in and out of the long-term play of the century (Bitcoin) or your SHTF insurance policy (gold).
I've a bit more respect for Zang-Bing after this post. The only substantive difference I have with this is that I consider BTC to be the speculative play of the century, gold to be the long-term one, and silver to the the SHTF insurance policy. For diversity and diversion I employ putter around with property of various types.
