It is not neccessary at all to have that bank because if we will be having it, I am expecting that goverment will regulate us , a lot of files are needed to be done and to be pass , every move that we will be doing will need their approval, there are some atm machines, I think it is enough , a private company without government rule is good.
You are right, if we refer to the fundamental reasons for the creation of Bitcoin then we will know that it is completely unnecessary, whereas cryptocurrency is for decentralization. So if you go back to the Bank system, it means that there is no change. And the expected privacy and anonymity will disappear. So let us maximize the existing order, whether there is legality or not, as long as it is not prohibited then we are free to express ourselves, right? so use this opportunity as best you can.
