No other exchange is going to list this crap scamcoin. It wouldn't be in their interest.
Trade vol. Is less than 1BTC per 24 hours. Do an exchanges commission at 0.25 - 0.5%. Pennies. Most people are proberbly gonna hold so there is really nothing in it for the exchanges.
I get as frustrated as anyone else when ICO's take millions of dollars and then don't take the simple, cheap steps of exchange listing. (Everyone could have bought PBT for a fraction of the price and they would have raised low/no money if ICO investors knew this before.)
Having said that, it's not crap or a scamcoin, they are working on schedule & it should be a valuable token in the medium term.
