If you look at the value of a bitcoin graphed over time, it looks an awful lot like a bubble. I sure wouldn't keep any assets in bitcoins. I've seen a lot of bubbles in my 44.5 years on this planet and this looks just like all the others (right down to the claims that "this time it's different"). The biggest difference here is that there is no underlying asset behind the bubble. Heck, even the lowliest failed dotcom had, at the least, some aeron chairs to liquidate when the share price hit zero.
