Rumors are rumors, and we do not know the truth. If you want, you can wait until the price reaches $1 and sell your Dogecoin. Maybe you can hold it for a while because the 11th is not too far from now so you can see what will happen later. You can buy more if you want, but be careful because Dogecoin can make a correction again, especially if the bitcoin price is down. But Coinbase can really accept Dogecoin as the other coins, so their members will have more coins to invest in Dogecoin.
