This is the case of having a better technology doesn't matter, Bitcoin came at a very lucky time and also grew organically for many years and had arguably the fairest coin distributions (most coins nowadays are shilled very heavily by it's developers and investors). It's also the most secure and well-known.
Because of those things, it'll be very difficult if not impossible to unseat Bitcoin when it comes to store of value/currency. Bitcoin also sees development in form of lightning network. For all other use cases, I think eth covers most bases and has also developed a very large network of users and developers.
So whatever next big crypto project comes needs to be not just "better", but like at least 10x better.
