Aren't you ignoring the fact that the two previous bubbles were artificialy made by MtGox?
After Gox closed the price just went down to where it should have been, and would have been, had there never been a MtGox.
Now hold on a minute, let's flesh this out. You believe the Willy bot
produced the 2013 spikes? What is your basis for this?
I don't know exactly how Marc did it.
But the price on Gox was alway higher than on all other exchanges, making all other follow. And when gox went away, so did the bubbles.
My guess would be that he just made the figures up, Willys part in that is unknown to me.
