As the title suggests i have some crypto in private wallet and i want to transfer it to CEX anonymously, what would be the best way to do so? I have a few options in mind but not sure if they are safe.

1. Use middlemen swapping service like changenow, changelly, etc..
2. Sell crypto for vouchers from wallet A and then sell vouchers again for crypto in wallet B (This should make it hard to link my wallet A to wallet b right?)

Any other way to do this even more anonymously?
