There is nothing connected between the twits of Dogenode and the movement of the price of Dogecoin. This is but a plain coincidence. Nothing more. In fact, no one should even exert effort trying to connect the two, they are completely irrelevant to each other. And if ever Dogecoin will gain upward movement, it will never be just caused by a twit of a random account which is not even officially connected to the project itself.
