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?
I will take the smartphone as a parable, for example smartphone with the brand of Apple is the most widely used smartphone by the residents. Later, another smartphone emerged that offers more features than the apple smartphone and the price is half the price of apple smartphones . But this is not so much affect on smara tphone sales because people who put quality is still more than people who only see the features and low prices. As with bitcoin and other cryptocurrencies, it's just a matter of trust not just brands.
