I hope you are right. I would like to see bitcoin go mainstream, even in australia, and it would be much more convenient if you could spend bitcoin in normal stores.
It would definitely be there at our local stores to be accepted for purchase anything but require some time to establish, we need to introduce it to everyone in our local community, so it will happen.
Bitcoin halving but don't forget the size issue. It'll be already good enough if we don't lose the biggest part of the value of btc. It's a very risky year so not the year for global adoption (in my opinion).
