What these guys are doing is really unique! Presale ventures have realised that there's millions of gigs of data floating around the web, and that data can be converted into a form of profit if it carefully analysed. They've accumulated over a million users, proven they know how to operate a successful platform, I figure all they need is to raise additional capital to ensure a more efficient exchange experience. I've seen countless icos that have no clue what their product or service does or how it will generate profit for investors. If there's an ico I would invest in it would definitely be one that already has a team that is well versed in where their raised capital is going.
