I mean, of course that's plausible. If I gave the impression that it wasn't, my bad. I was just hoping to clarify to eugeniub why BTC enjoys a first mover advantage, and why first mover advantage has nothing to do with how often "people use it in their everyday lives".

Assuming a limited amount of resources to invest, someone who is already invested in X, is less likely to remove their money from that and invest into Y, unless Y is really good. All things equal, there is no reason to move from X to Y if X came first and you already invested into X.

So, the first mover advantage for BTC is the fact that new coins need not only be equal (in the eyes of the investor) to BTC, but better enough to convince that investor to move out of BTC in favor of that coin. People who are, in addition, buying other alt coins are still solidifying BTC's first mover advantage if they do not remove their investment in BTC in favor of something else.
