Polymarket runs on Polygon, which, like most blockchains, has public history. If the user wasn't very careful about how they got their money into the system, it traces back to a public cryptocurrency exchange with KYC records.
That's the BS reply that always comes when (in particular) bitcoin is associated with crime: that it is traceable. Well, it hardly is. And for the average policeman/woman, even less so. And when the owner has taken some care, as you admit, practically impossible even for experts.
...so then trace the transfer to each identity? How does knowing the first person in the chain help identify the 2nd and 3rd, etc? What if there are 50 identities and the coin has a dozen origins?
