It was just a Coinmarketcap bug. No fault of PAC. CMC used the old coin count and the new price, causing a 1000x jump in market cap.
i think they faked a transaction on separated chain? so it looked like 5M BTC on project. Possible?
That's why CMP sucks right now! Coinmarketcap must have made a mistake, PAC coin appeared #3 on CMC WTF ( I was wondering the same thing, how it will grow that much??) and then disappeared.
You can't expect a fast update of the rebranding or swapping of PAC and any other coins. We don't know how mamy people are there to work and most importantly is to confirm everything before they change and update paccoin is not the only coin whose contacting them. Have patience it will all fixed.
