I'm not sure but that guy, Kim Dotcom or whoever is a bit problematic guy in the eyes of USA law. I think there are several cases ongoing about him. He's a big fan of bitcoin but I'm afraid of him to damage bitcoin's image becauase his history.
Hope he can manage this and desn't damage bitcoin's image. His business would be a opportunity for bitcoin too.
To be fair, Bitcoin doesn't have the hold reputation in the eye of the public, there are many people who associate Bitcoin with drug traffickers, money laundering, illicit weapons sales and pretty much anything illegal that you can find in the Dark Web.
About Megaupload 2, as far as I know the website is going to be called "K.im" and honestly, it sounds like a promising project, though its success will be based on how many people are willing to pay for content that they can find for free online since this website is going to be a file hosting service and will be used for piracy.
It could definitly help Bitcoin become mainstream, since the site also includes the option to monetize files using Bitcoin micro-transaction as payment. imagine YouTube creators or indie musicians using this website, it could be a game changer. But unfortunately Kim Dotcom has stated that the site will go live after the ICO so...yeah.
