Vote for PIGGY on Livecoin, another exchange for the purposes of less centralisation! https://www.livecoin.net/voting/index?vote=Piggycoin
You can vote for free once a month, but you have to have an active account. They consider an account to be active if any money has ever been sent there, even as little as 5 DOGE perhaps.
It’s not necessary to outright win the vote as they pick coins to list from the top 3 or so.
