Bitcoin weirdness

Until 2140, you'll be fine

I'm fine now - I don't have any bitcoins.

Seriously though, putting money into something 'because there's no real way to find out what a fair price for it is' seems to me to be rather a gamble. Particularly when it has no intrinsic value at all, which would seem to imply that the 'fair price' is actually zero. As for the claims of the bitcoin-promoters, obviously they will state that this isn't a bubble - as did the promoters of every previous bubble. And no doubt come the next bubble, the claims made will be the same...
