It's really hard to argue against Bitcoin with whatever currency.. escpecially Dogecoin. The fact is that BTC has been the first in the market, and has the first mover advantage, which is very important. Microsoft had the first mover advantage as well when they lauched the PC (personal computer) and now decades later people are still using Windows (a microsoft product) and it become very difficult to change the Windows operating system, with, let's say Apple OS, which might be the best operating system, but since microsoft was first and introduced Windows, people got used to it, and people don't like change so they stick to Windows even if there are better operating systems out there. Same goes for Bitcoin.
