I like how you approached the prompt, it is possible but such things cannot be of advantage to the whole world now because we are not ready. Firstly, not everyone believes in this crypto thing, especially the elderly, sounds so strange to them. Secondly, one would need access to a phone, or a computer to make transactions, thirdly, access to steady internet connection and electricity is crucial. I'm certain there are still many countries facing these problems. Hence, it won't benefit the whole world.

Maybe next, 20, 30 or 40 years from now.
