This is a really good point, I hadn't thought of this before. Because of how many other options there are, the "scarcity" of Bitcoin is only real if there is something that is going to prevent other cryptocurrencies from being used, or promote Bitcoin above all others. Given that Bitcoin has been demonstrated to be inferior at scale vs. some of the other options, I don't see a reason to expect that it will continue to be the most prolific in the long term. By extension, there doesn't seem to be an obvious indication that any of them will see a lot of use in the long term.

It’s especially important when you think about mainstream adoption: the assumption is that the whole world will pile on board and make the early adopters fabulously rich but it seems at least as likely that some major companies would create their own alternative – possibly using the same software — and heavily promote it through their existing merchant accounts, cards, etc. rather be than letting someone else capture that profit.

Right now, the lack of consumer demand means there’s no reason to bother but if that changes I’d be surprised if nobody tried and there’s little lock-in to prevent people from bailing to whoever gives better terms.
