Yes we know Dogecoin was created as a joke but from a technical standpoint has almost the same code base as litecoin or Bitcoin I forget...so it would be pretty easy for them to catch it up just as pivx did awhile back. Speaking of copying... Proof of stake copied from another coin, master node, copied from dash, privacy? Copied from zcash. Don’t hate another crypto just because it’s funny or a joke and shouldn’t be taken serious. That’s exactly what Dogecoin is for. Go look at their Reddit they know they are not serious and funny is their game. However you can buy a car with it, buy lots of stuff with it...it is a crypto and a damn good one.
