It's complicated, comes with transaction fees, isn't quick, but will work. I'm assuming that if your are worried about the authorities finding out then it's not going to be a small amount of ETH so the small fees really shouldn't matter. May cost you another 10% but should leave as little a paper trail as possible. Why do I feel like i need to go wash my hands now.
Thank you for this, I already tried this and works so fine. I really appreciated your post here in my thread. I'm really thankful for your advice. I just wasted only few ethereum for transactions on the exchange for withdrawing it. But all in all is smooth.
