Did the 2011 and 2013 bubbles pop because of MtGox ?
In 2011, MtGox was hacked *after* the price crashed to ~18, or 10 days after.
In 2013, the lag was bad, but it wasn't anything new. It was mostly felt on the way down.
I agree with this!
No one is denying that Gox has become a terrible service plagued with problems. But the popping of bubbles is not their fault. The lag only kicks in after orders begin processing. The ddos was not the cause of the burst either. If anything, the lag/ddos slowed the sell-off, otherwise we may have seen $10 after the ensuing panic. The lag and the "cool off period" allowed people to rethink their decision to panic sell.
