In contrast, there?s no significant community of people who conduct commerce exclusively (or even primarily) in Bitcions. And you can?t eat, live in, or make jewelry out of Bitcions. And this means there?s no logical stopping point to Bitcoin?s price decline. So far Bitcoin enthusiasts have been buying Bitcoins as the price falls, convinced that the price will go back up eventually. But as the hoped-for rally has failed to materialize, more have gotten discouraged or bored and cash out, pushing the price down further. This process has been going on for a couple of months, and now it appears to be accelerating. I suspect it?s terminal.
