I really doubt we are miing doge coin due to liquidity unless there are private buyers out there which I also doubt but anyway ...If we are mining doge coin at one point or another here is another exchange for it.

Dogecoin has been introduced for trading#DOGE #dogecoin
like i said on the last page, with the profit we're making, block times, and the calculated difficulty there isn't anything else we could be mining. Unless as someone else claimed that h20 could be feeding us false difficulties, but then the question would be what else is this profitable right now?
