I'm not sure how huobi is capitalizing in there but I think they've taken advantage of the pi holders believing that they have it. But it was clearly explained by them that it was also an IOU so they simply rode the hype while there's a volume on it. Until now, there's no clear exchange for the actua PI coin that have been there for so long and that's why many have been calling it as a scam and even I, I don't think people should put their hopes on it.
