MegaUpload will re-launch on January 19th on the new domain
www.me.gaOn the site it says they are looking for investors to get in touch, but nothing about bitcoins.
On the other hand, it doesn't state how to invest, so maybe they do accept bitcoins.
It's not completely clear to me either, if the new mega upload will work like the old one.
Piracy aside, I do miss a place to upload large files to, for sharing with friends and family, so I hope they have figured/are figuring out a way for Mega to stay legal, safe and functional.
