There's tension between bitcoin and gold.
Why is gold such a stable holder of value? Why does it have any value? These questions have all been asked and answered and it comes down to agreement. People have constantly agreed to value gold for millennia, so gold has value.
Now enter bitcoin. Why would anybody compare bitcoin to gold? And yet the comparison is made frequently. But of course it's brand new, so we have no history to study.
I feel this tension in myself. I know something bad is coming. I want to put what I have into something that will withstand the coming cataclysm. If I load up my house with gold, it will greatly increase the chances that I'll lose it any number of ways, and maybe my life too.
Bitcoin would allow me to put all the wealth I choose to muster, encrypted and replicated onto thumb drives, hard disks and cloud sites. In that way it's much, much better than gold.
But the obvious question is whether everyone will agree that bitcoin has maintained it's value by the time I need it. And whether the infrastructure will survive the storm intact.
All this speculation will become very relevant later this year when COIN, the Winklevoss Bitcoin ETF is expected to become available for investment. That can't help but drive up the value of bitcoin. And there will also be competition from SecondMarket's BIT ETF.
So if anyone is weighing PMs against bitcoin, the time to decide is rushing toward us.
