Don't worry, Binance exchange can withdraw 2 BTC daily without KYC. in this case you still anonymous.
Not really. They have your IP, your browser fingerprint, your location and so on. Can't call "anonymous" a website that logs data which could easily be used to identify you.
I am okay about that, I will pay tax and I will be a good citizen. I am a young boy who only has a small balance, never withdrawing more than 0.1 BTC.

. I won't make my life more complicated.
