I read an article that detailed how DOGE cost of maintenance is higher than any other coin. I don't know how credible it was, but the gist of the passage is that because so many DOGEcoins come into existence so quickly, the coin will basically be fighting crippling inflation all the way up.
But even as I type that I'm not sure I believe it.
It was written by a Quark supporter after all
Due to Dogecoin's fast block schedule, its cost of maintenance halves every two months. It's already down to $360,000 from $720,000 previously, and will fall to $180,000 in April. It's quickly becoming sustainable.
