Bitcoin is the oldest and most valuable cryptocurrency, but a crop of nimble competitors, including Ethereum and Bitcoin Cash, could lure investors away.
if I personally think that there are no other coins that can take the crown from Bitcoin, because now Bitcoin is a king of all cryptocurrency, I can say that because I don't think there is a coin worth replacing Bitcoin, but I also cannot confirm that Bitcoin will be the king of cryptocurrency forever, because I am sure that someday there will certainly be another coin can take the crown from Bitcoin, but for now there is still no one coin can replace Bitcoin.
