It's a success if you consider the pump&dump that made him make a lot of money.
Not really. Moneros price is barely 10% higher than the low caused by the attack. If anything the attack was psychological and is still having ramifications as we speak.
I have to agree with this. Cryptocoins trade on rumours and hype so even if BCX was completely full of hot air, he certainly caused damage. Sure, the price didn't plummet but there is no telling how many people were stopped from jumping in now, or even turned off forever.
