It seems so, when many altcoin made their competing so bitcoin keep speeding ahead. Altcoins too emerge as an development in technology based on the same blockchain technology.
Altcoins are built not because of the competiton but because they do offer other service that bitcoin does not have . That is the reason why they are called alt or alternative coins because they can be used as an alternative next to bitcoin if you are not satisfied the services offered by bitcoin.
People do often mistakin that cryptos are in a competition because of their prices that may seem to change . They can rise or fall and they can surpass each others ranking because of price change but that is probably normal and that is only the effect of volatility.
