(Will a 100% Stable "Quantum" Financial System make the Digital Banking System and Cryptocurrencies "obsolete"...???) If we talk about stability, obviously cryptocurrencies will disappear. I hope this does not happen. Many people, including the owners of banks, are already involved in this . It accumulates and is manipulated. This is the bad thing about this. The economy is really manipulated, but cryptocurrencies are manipulated on a large scale.
