A lot of people think that only bitcoin will be enough for the masses to use, but why they don't stop for a moment and think about the car industry for example, in the car industry we not only have Ford cars, we have Nissan, Mercedez, etc. same applies to crypto, there is room for more than one coin, not just bitcoin, but many altcoins too, those thinking that only bitcoin can make it are completely wrong, thus they are called bitcoin maximalists.
