so would that be a feature of monero-to-monero transactions? I'm still confused as to how it would actually be anonymous? like if I used another coin to exchange for monero, that's obviously traceable. so then I use monero to purchase something else which I then sell for other monero (or I just trade monero directly? if that's possible?). and I'm to believe that there's no way to trace that back and say "okay, monero from wallet X was traded to wallet Y" or whatever other intermediate steps (like"monero was spent on X from wallet A, and then X was resold using monero from wallet B")? like, assuming they don't get in to my wallet, no one would be able to track down a transaction on the chain to a wallet? Or they would be able to track it to a wallet, but they couldn't tie that wallet to me for... some reason?

sorry to ask, but the website seems very light on any actual technical detail about how they are achieving their privacy claims - at least in terms I can parse to make them understandable to me.
