If the government still doesn't know how to put down all cryptocurrencies(or maybe they're still figuring how to tax users), why wouldn't they create an exchange and get some profit from it?
We know how B.S some exchanges are, they needed KYC but in the end, you won't be able to withdraw your funds.
Instead of spreading FUD, I hope government from all over the world knows that running an exchange can add funds for their country, and their pockets!
I know it will be making cryptos centralized but look at those exchanges asking for our pretty faces and names just for their KYC/AML purposes.
Those exchange that requiring their users to submit KYC was just a normal things if they are under the control of the government due to they are centralized exchange it is because of AML, at least by giving our KYC to them is not a problem at all. And I just want to clarify something which you just said in the above that
" They needed KYC but in the end, you won't be able to withdraw your funds " You can't able to withdraw it, maybe because you didn't comply completely the requirements for the KYC to that exchange, because once you complete it, you can now able to withdraw your balance fund you have their any time you want.
