Well , i would say if XMR is a lot more than just a little bit. Just how you use it like everything else , theres a great video on tankietube from people who try and track cryptotransfers. Very educational.
If it is very sensitive and you do an extra transfer i would say its foolproof.
Theres a reasons governments around the world are cracking down on it. Or at least try so and make it a bit more difficult to buy it with fiat. Also just regular BTC can be tumbled.
When people say its traceable yea , but to where? For me my phone is traceable but it ends there , its not traceable to me. Unless I got someone stalking me physically etc. Crypto is the same but easier. Its traceable to an anon wallet.
For boiling the oceans , well yea but not near to the amount that the fiat system does.. So I put this in the same category as moving to a cave to escape capitalism.
