Yes i think bitcoin really has no competition, why? Bitcoin hasbthe largest amount and value of currency, and bitcoin is the largest cryptocurrency that ever existed, the gap of bitcoin to other crypto is very far, the ethereum that is an altcoin is only the 50%amount of bitcoin and that is a very high gap, so i conclude that the second to the highest crypto has nothing to do and to compete with the largest cryptocyrrency which is the bitcoin, we cannot say that ethereum can really pass to bitcoin.
