Litecoin is faster, monero is more private, ETH has smart contracts and there are much more altcoin with much more features, even Bitcoin Cash is faster than Bitcoin, but BTC keeps rising much faster.
Don't you think it's just because of the name?
No it's not the name of bitcoin why it became famous and valuable. It is the acceptace of community through it's nature,uses and quality. The demand became huge which bring bitcoin at the top of the throne with only a limited supply. Unlike other coins that has a large amount or unlimited supply,the value is not worth because coin market always depends on the law of demand and supply in order to have a value.
