Sure, appcoins will probably have some value but it will degrade over time, just like frequent flyer miles as they will inevitably be inflated away through promises broken.
i am guna laugh my god damn ass off if an "app coin" as you call them ever over takes bitcoin lol im not saying its likely, just that it would be the most hilarious event in crypto history for me to see so many "wise men" proven wrong all in one go
How could they as most of them have not guaranteed a fixed supply nor will function as a neutral SOV for an undefined purpose.
The way this would happen is if one of them became extremely useful and popular first. Then it would be so widely used and accepted that it could start to be used as money by others even if they had no direct interest in the underlying service. It really wouldn't take a lot for something to become more widely used than bitcoin at this point.
I don't really see this happening with something like storj (too limited in application), but something like ethereum or perhaps maidsafe has the (long shot) potential to develop in that manner.
You are looking at this in terms of what can be done (i.e. can be built on bitcoin), I'm looking at it in terms of what may actually happen.
Systems like ethereum or maidsafe could possibly become vastly more widespread than bitcoin on an explosive basis (i.e. far faster than bitcoin can adapt, if there is even a desire by the bitcoin community to adapt). Vastly more popular means only tens of millions of users or possibly 100 million, which really isn't that many when you consider something a simple application like whatsapp with a billion users.
At that point the liquidity argument usually made in favor of bitcoin applies strongly against it.
To be clear I don't expect this to happen, but i recognize it as a possible low probability outcome.
