Unfortunately, cash is slowly getting phased out.
Try buying a second hand car and you want cash from the bank. Used to be very easy, but now you need to declare what your spending your money on.
You sold your car. O, its over 7 or 10k, well, this is getting reported to the local IRS. Where is that cash coming from, questions, questions?
Over here they are even cracking down on stuff like ebay, amazon because some people run a business on those sites and do not report the taxes. Result: If you make over 3k in the year on ebay, you need to provided your tax number, or ebay closes your account. And above 3k, it get reported to the IRS.
But wait, what happens if your a foreign national from some specific Asian countries and want to open a bank account? Refused, refused, refused... But you need a bank account for a lot of basic things. Well, tough luck. Lets not talk account closing issues.
And that is the EU, and just normal people. Nothing tax evasion, guns, or whatever. Just everybody putting up umbrella's to be sure, not understanding that when everybody does it, it really screws with people.
They are going crazy with this over regulation. Yes, i understand you want to fight black money but the people who get the big amounts will have ways to hide it. Your just hurting the normal people wanting to know what everybody is doing exactly with every cent.
You see this gradual effort to slowly phase out cash. Cashless payment are getting encouraged, cash withdrawals cost your money more and more, more questions regarding origins (so you say f it, and use bank deposits with release approvals).
Its not a surprise that we seen the increase in cryto usage (and the efforts of governments to control that also).
