First mover advantage still requires some reason to stick, especially when it costs more. Almost nobody _needs_ Bitcoin – most people don’t use it at all so they have no reason to pay more for it and there’s almost no situation where that would be the only option. The only reason to buy in is hoping that there will be more demand in the future, and that can evaporate quickly as we’ve seen because a fiat currency like Bitcoin is valued on the strength of its backers and it doesn’t have anything like a country or large industry driving demand.
