I totally agree. A cryptocurrency is a universal currency but lets go ahead and compare it to a national currency anyway. If a country had multiple forms of currency it would do nothing but dilute the value of each and every seperate currency and it would cause economic chaos really. Which is why MOST countries stay away from that, and when they come out with new technology for the currency they do away with the old. Which is how cryptocurrency should work also, If one is better because of an advancment then naturally it should take the forefront. But there should not be multiple forms of essentially the same currency with absolutely no difference but the name. It dilutes the market and its main purpose is to just trick newbie investors who don't have a clue.
