So creating a cryptocurrency exchange platform that is registered company is completely legal, even if KYC and SOF (Source of funds) are never required, providing maximum anonymity to its' users?
That's how it should be and these are some basic principles of Bitcoin and cryptocurrencies.
It is something else entirely that the narrative of mandatory KYC was created due to the fight against illegal business and crime, although this is most often applied to have a better insight into all money flows, most often legal ones. If money flows were free and in privacy, on what basis would governments charge taxes?
Also, the area is quite undefined, and even though no-kyc exchangers are legal, they can be interpreted as illegal somewhere.
Well, if non-KYC cryptocurrency exchange platform is legally registered company in country where laws are interpretating it as legal, it means operators of that service cannot get in legal trouble?
Only one who "can" get in legal troubles are individuals that are using this service despite service being interpreted as illegal in their country, right? Also, I assume that running .onion hidden service of completely legally registered company of non-KYC cryptocurrency exchanger is fine.
