It's been written some posts above. Two reasons: DOGE trading on yahoo finance and Dogethereum.
Dogeethereum, really?
I don't know how DogeEthereum correlated to Dogecoin, our favorite coin.
Yahoo Finance is breaking news which plays important role for latest exponential rises of Dogecoin.
I heard somewhere someone posted that Dogecoin might dissapear someday. I don't believe it will happen at any odds.
It is a sort of fudding effort.
Everyone, did you know that poloniex exchange has enabled DOGE coin trading pair with USDT? It is really convenient for traders, so it price can not stop rocketing soon.
