Interesting data, but it also shows why privacy and self-custody matter so much. On-chain analysis can reveal a lot, but the real lesson is: protect your keys, generate your seeds properly, and donβt rely on third parties. Stay sovereign.
@Dr. The Daniel π the exchange origin part is the bit worth sitting with. a withdrawal address ties a stack to a kyc record permanently, so the wallet flaw only told an attacker which of those records was worth acting on.
I already said how they know. Canadian people bought KYC bitcoin on Canadian exchanges and sent it to the address on their ColdCards. This isnβt hard.
To be fair I also have trouble fully understanding, if I buy at an exchange and the sats move wallets a couple of times, but just as the same custodian vs as part of an trade ? Anyways the root origin from a Canadian exchange is already some signal π€
