Proof of bandwidth is an innovate idea in the cryptocurrency space, but it seems a weak point is "make money selling them on the exchange". If that is their only value - if there is no economy built around them and they have no purchasing power on their own - then they'd only see a brief pump-and-dump rise/fall like any other new altcoin. Certainly it's an experiment worth trying, but if its sole value is in its potential for exchange, I don't see anything preventing it from becoming yet another short-lived altcoin. Then again, the same could be said of many coins out there now that have been lingering whole weeks* without dropping to 0 value 1. some have even been surviving for months...
