Every exchange is. Because they must obey the law, otherwise government will shut them down. So they have to obey those regulations such as anti terrorism, anti money laundry, etc etc... they must then ask you where your money comes from (anual income), documents, ID, address, etc... Just like a bank..
My main concern is not about privacy (this is completely lost in exchanges already). But i am worried about my funds beign frozen or the exchange hacked.
There are many reasons a government may want to frozen funds in an exchange.
Maybe that exchange in involved in money laundry (or is under investigation), or new law in the country it is based comes up baning bitcoin transactions, or whatever. There are things that are out of our control, even if you are an honest guy doing everything by the book (especially in this ecosystem that is full of scammers)
