I am a believer too, Bitcoin shows a lot of potential, sadly many businesses do not accept it and it is somewhat less convenient to pull out your phone for every payment, the battery can run out, it can break, etc etc.
Hopefully in the future they will find a way to send it person to person more easily. That would be the first step.
I think the conference will have a lot of exciting prospects as well as plenty of new ideas bounced around and networking to help get that kind of infrastructure off the ground.
A really good, secure hardware wallet that is more usable by the average consumer will absolutely take BTC to the stratosphere.
