Dogecoins as of now where advised to be dead a couple of years prior and they are as yet alive Smiley. There isn't just a major network. Doge is a decent money to be utilized for exchanges as a result of low charges, stable wallets and quick exchanges. Case: If I need to exchange bitcoins starting with one exchanger then onto the next, I don't exchange btc specifically yet trade initially to doge, send and after that trade back to btc.
