As we all know, most of the crypto currencies (especially bitcoin) are decentralized and anonymous.
That's where you're wrong buddy. It's actually the reverse. Pretty much all cryptocurrencies(yes, even Ethereum) besides bitcoin is centralized, and probably 99% or more of cryptocurrencies are only pseudonymous.Why should those exchanges collect our personal information? Do you think KYC is necessary?
If you ask me, of course I wouldn't want to submit KYC. But the fact is, most governments of these countries that these exchanges operate on requires KYC. It's not like most of them require KYC just because they want to; most of them are just following the government requirements.Lol, you are right. I made a mistake. Only BTC isn't under the ctrl of someone like the founder Nakamoto Satoshi, and no one knows who is him.
