Thanks for sharing this, @marketingmonk.

Okay, so far, the constant is 40-45%, judging by correction indices.
I'm very interested in what variables will play into a 50% cut of that 40% value, to reduce it to 20-25%.
That's probably when Bitcoin (and along with it, other coins) will become more stable. And by stable, I mean knowing that if you invest "n" amount, the losses and gains will have a confidence interval of [-25%, +75%] for values between 0 and 50 (if we consider the 50% value).

To some extent, this is what they want to achieve with Bitcoin futures, but that's a whole different game.
