Bitcoin is a service, and as such, only has value to the degree that that service is 'moat-able.'

When they can dig a moat, I'll take interest. But right now, they are a hackable hack product -- that *happens* to be fashionable. (Much like YHOO ate AOL's lunch, long ago. And MySPace ('Remember them?!?") drank YHOO's milkshake way back when. And how FB has completely p'owned MySpace & YHOO, and how, out there right now, is another party, looking at some service provider (LNKD?? MeetUp??) with a cludgy platform and an intrusive and hungry data engine, and sayyyyyyy, "Nope! You guys SUCK! We can do it better!" and the moat-breaching commences.

Bitcoin is a freakin' tulip. I'm not sayin' it's not *pretty!!! But it's jus' a freakin' flower. And with a smidge of time, "If you don't sell me the bulbs I want, I'll jus' go down the road to the next stand...."
(And for the record, GOOG is in there, too -- both in terms of Milkshake Drinkers, AND in terms of .....shallow-moated technologies that I would recommend for investment only on the basis of earnings, earnings, and, oh yeah, earnings.)
