I have seen a commercial yesterday that showed that if you use your banks app you can actually pay anything via QR code on the POS machine which means instead of carrying your credit card or debit card with you all you have to carry is your phone which we already carry anyway.

Now that really changed my perspective on bitcoin as well, if we have that technology for banks today why not have the same thing for bitcoins as well, there was just few exchanges for bitcoin at first but almost all countries have their own exchanges today, so if someone actually makes an app that pays with bitcoin thanks to QR code thing and the receiver gets fiat to their bank account than that app will be SUPER hyped and everyone will start to use it everywhere which will make adoption super fast and all other countries will see how that was done and replicate it as well.
