Maybe this will happen when other countries do the same. Other payment methods will be applied such as credit card, ATM, debit card and pay by phone. The telephone payment method is being used by phone manufacturers such as Samsung, Apple, etc. It is a new form, fast and anti-theft. We can also apply payment by scanning the QR code via the phone. And in almost a few years, we really do not need cash because we have digital money
We will always need cash.
Please remember folks that atms and electronic payments methods are only ubiquitous features of first and second world economies. There is not connectivity in all of the third world; hell thtere isnt even electricity, fuck connectivity. it will take many more decades and muuch more globalization to get to the point where we would consider atm access a "feature" of third world life. Running water isnt even a "feature", as well as dependable access to food and health care. Since fiat has been working just swell up to this point, I dont really see a clear incentive for government adoption. How do you print more bitcoin when you need to swell your currency supply? And how do you stop money from leaving your borders and enriching a rival State?
You can't.
You can find SMS recieving cheap nokia phones all over the third world. With satellites, such as the one that Blockstream launched, you already have connectivity to the blockchain.
This is still very early in the game, but you can already tell the fact that steps in this direction are already being taken. In the future, you will be able to both receive and send with the satellite. Eventually transactions in North Korea will be happening too, with people smuggling phones and gear across the border in an underground fashion.
It is a matter of time everyone on earth is connected to the bitcoin blockchain and no government will be able to stop it.
