More and more people are using smartphones thanks to budget friendly mid-rangers, almost anyone can now afford to buy a smartphone.
Mobile payment is becoming more common and it is an opportunity to acquaint people more into using bitcoin . Mobile payment will eventually replace credit cards or at least will make them less mainstream. An example of this is Apple Pay. Bitcoin smartphone wallet apps are to use when you have a transaction, you just scan a qr code and the transaction is done though will take some time to be confirmed.
I would agree.
But not just smartphones, but phones in general.
People, are able to use even non-smartphones in rural areas because they don't have internet access. They can send a text message to a service that allows them to do bitcoin transactions without internet access, and then the service provider sends the bitcoin for them.
Phones are just so much more portable now than laptops or PCs.
Even the people in rural places are having a successful growth and most of the rural places here in our country (for example) aree having an internet access and they can afford more than their past lifestyle. I think this is a good sign that they also use bitcoin even they are in the rural places. They just need internet access which they have an average smartphone to be able to do transactions.
