Pump and dump coins don't need wallets. You keep them on your exchange account until you dump them.
I can't believe there still are retards out there, who actually believe ethereum is a pump & dump. I mean Vitalik wanted those features on Bitcoin itself. Also the ICO was open to anyone. Jesus...
Go get a beer and loosen up watching stagnating bitcoin getting passed by 3 or 4 other cryptos in the next couple years or so.
