I would have thought about it if I knew the supply was only limited to 21 million Bitcoins and it can he find trhough mining. Dogecoin has +100 BILLION coins available, so it's way easier to get a Dogecoin than it is to get Bitcoin. If everyone in the world would use Bitcoin, there would be around 0.0003BTC available for one person which would make it extremely rare to own a Bitcoin, whole there would be +14 Dogecoins available if it would be used instead. The more rare it is, the higher value it gets. So Dogecoin has a smaller chance to reach a higher price in my opinion. If it would, it would be like copper and Bitcoin would be the gold.
