Digital currency is coming
Technically digital currency is always similar regardless is it made by a private or governmental actor.
Digital currency is a long decimal number, that is secured by using the digital secure algorithm. That algorithm multiplicates the number series by using the extremely long quantum decimal number, which can involve thousands or millions of numbers. That kind of currency could be the same way safe, with the normal currency, if somebody would not steal that quantum decimal number and install it in its server, which means that the server can make very much new bit currency units.
The Internet makes money transfer easy, and the thing, how we see that thing is that if we would use computers also traditional currencies are acting like one digital currency. The computer can calculate the exchange course in seconds and update it many times in second.
So transforming every currency across the border is easy, and the internet allows that bank accounts and other things can be operated from the other countries, and that's why the central banks must also advance digital currency. If the central bank would release a digital currency, it can control the use of that money. And if digital currency is in the bank account at a foreign land, the central bank can delete those virtual banknotes by pushing the "delete" button.
But how to make sure that nobody makes own digital money by using stolen secure code?
The thing is that in real life the "gate" where the legal services will be connected could mark the bit line by using the security code, which tells that the digital money is properly made by using legal systems. So the digital currency can be even more secure than the normal cash, but the problem is that digital money can be used to track people and those series of bytes are computer programs. The digital money can tell everything that a person buy to the deliverer, and that is problematic with privacy.
But printing traditional money is also expensive. Every single banknote must be equipped with the holographic mark and that makes them hard to fake. And the high-qualified printing product is always expensive. Also, banknotes are good targets for robbery. The use of encrypted currency is similar to using the bank- or credit card. And the advantage would go to cryptocurrency, what is the digital version of the normal currency.
The thing is that every single banknote and the goods, that are bought by using them can be tracked by using surveillance cameras. The face recognition software can track people in seconds if they have access to the registers, where is stored the face images of the ID-card owners and personal data of those people.
If the banknote is equipped with RFID-chip, that thing can be read by a regular mobile telephone. And that thing can also compare the RFID-data with the bank databases. But also the ATM can be equipped with an illegal RFID-reader, and that system can share that data through the internet to other mobile systems. So that thing can be used to track people, who wanted to hide something that they are buying.
The physical banknotes can also be tracked quite easily, and that makes them problematic.
When some people are buying merchandise by using cash, the surveillance camera can take pictures of the person, merchandise and the system, what makes sure, that banknote is legal tender, can copy the serial number of banknote. Then the system can check what bank card, and who owns that card has been used to take that banknote out from ATM. This means that the normal banknote can be as well dangerous for privacy as some digital currency.
The reason why currency wanted to transform digitally is that digital currency eliminates the problems, what artificial cryptocurrencies are causing. The cryptocurrency, which is controlled by central banks can be eliminated by pressing the button, which makes illegal trade by using that currency impossible. Crypto- or virtual version of currency doesn't require massive security deals, and that means that the use of weapons in the robbery is unnecessary.
