I don't think the next spike can be $560,000 14 months from the date of the OP. That's next November and would have to go up from today's price by 2240x. It's never done anything like that since it went from 10 Bitcoins a cent to $2 when it started off. Those kind of price increases would need billions of dollars throwing at Bitcoin to happen today. In the early days a few thousand dollars would pump the price crazily.

So the number I have picked is probably not that accurate. The magnitude, and the colossal unbeleivableness of it, is what is important. That's the black swan that nobody sees coming. That 90% of the people in the world will miss 90% of the bitcoin

Probably my timescale is wrong, probably my target is wrong.

Mostly though I'm still confident the underlying hypothesis remains solid. When it happens people will be utterly bamboozled.
