Who sells dogecoin for the price?
You can get it there in an exchange. Coinexchange has it.
I'll give advice, do not buy. This coin does not have a good future. There are no updates that would contribute to the growth of the coin
What if an update starts coming up and someone already has one million unit ? What do you think will happen in that instance?
Sometimes one do not have to hussle so much for wealth to come. A policy that is positive to an individual's investment, is capable to turn such person's fortune for good.
