So there can be a category of people who consider themselves BTC/ETH Maximalists.
I am one of them and we are many in this community, I love these two coins that sometimes i think that I only need these two coins to hodl and I will be ok, but we need to increase our portfolio and not to put all our eggs in one basket, so I still include some coins in my portfolio, but Bitcoin and Ethereum are two coins that makes the bulk of my portfolio.
