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?
Its not because of the name. The reason why bitcoin is still at the top 1 crypto based on coinmarketcap is because bitcoin is the father/mother of all crypto currency. ETH,XMR,BCH and LTC are just a copy of bitcoin in upgraded manner.
And because of this. bitcoin becomes the digital storage of wealth. Thats the real reason
