If you're going to buy a privacy coin like Monero it would be smarter to transfer it on-chain after Binance sent it to you. That way you get the privacy of a Binance hot-wallet in addition to the privacy of all of Monero's decentralized tech. Combining both of these features make the money almost completely untraceable (especially considering how underfunded the tax man is). You should also be using a VPN the entire time and perhaps not even be making the transaction from home (or even from a computer you own). It also wouldn't hurt to create a new Binance account that's also not connected to any of your hardware or IP addresses or email accounts.

All this being said you'd have to be moving quite a bit of money around for all these tactics to be worth it imo.
