Perhaps, with the increased traction of blockchain acceptance nowadays, could lead to the creation of digital fiat currencies powered by blockchains that are managed by governments themselves. With this in mind, there would be no need for physical cash, as digital fiat currencies would provide many advantages such as quick settlement, global payments, full transparency, implants use on citizens to make payments, and more.
If this becomes a reality, which I'm sure that it will, it would radically transform our lives for the better and reduce criminal activity as a result of the full transparency and auditability that a digital fiat currency would have thanks to the power of the blockchain technology.
Also, it makes me wonder if cryptocurrencies like Bitcoin would exist by that time, or will they co-exist with digital fiat currencies.
Nevertheless, I would like to know your opinion about this.
If in the future is a cashless society then it will be a great thing that will happen. Imagine that in every transactions has a record then all illegal transaction can be monitored and be identified and that helps the crime prevention and crime solution in this world.
