Bitcoin is the oldest and most valuable cryptocurrency, but a crop of nimble competitors, including Ethereum and Bitcoin Cash, could lure investors away.
It will only happen if there will be a coin created with a much better platform than bitcoin. Bitcoin today can be considered as the mother of all cryptocurrency it has the highest value among all the other coins. It will not be very easy to dethrone bitcoin as the number one cryptocurrency because it is the oldest and maybe we can say stable and established crypto around the world. Until now it is impossible to happen but maybe in the future as technology continues to develop more.
