I think that coinbase undergoes full KYC/AML vetting procedure (takes a month).
This depends on your country, bank and degree of fascism you are subject to. Here in Sweden, for example, the banks view "activity" as "suspicious" until you prove otherwise and doing so is not that easy.
I have a Norwegian neighbor who is in her 70s. She has saved up quite a lot of money during her long life. She tried moving some of her money from her Norwegian account to the local bank. They froze her account and demanded all kinds of statements. It was apparently not enough to show that she bought a big fancy house in the 1990s and sold it before moving to an apartment here mid 2000s. Where did she get the money for that house? By selling another house when she moved at that time. But the documents for that was not enough. No, where did she get the money for the house she had way back in the 1970s? And so on. She eventually gave up and closed her local bank accounts.
It does not matter if you made your money legally or not, all bank activity is now "suspicious".
Are you sure that you are not exaggerating anything here? Wouldn't that completely impede the capital movement, which is a large %% of economy?
If what you are writing is true, then i understand where Cyprus came from.
