Hi -
I don't believe Bitcoin is in need of a killer app. I belive Bitcoin is in need of a killer incentive.
Without incentive to use the currency in the first place, the general public is never going to use any "killer apps" that become available.
Circle could be the easiest thing ever to hit the Bitcoin space. If consumers don't give a fuck about Bitcoin, they aren't going to use Circle.
It will simply be a killer app for people already in the Bitcoin ecosystem.

Agreed! It's up to the specific industries adopting it to give back to the community and provide their own value adding incentives. But I think apps like Circle bring everything to life and simplify the process. If your bored check out
