I remember when Bitcoin first came out and one of the selling points of bitcoin was that literally anyone could trace the transfers using the wallet codes and what not no? I don’t ever remember there being claims that it was untraceable at least as the selling point to the average consumer. There was even tools in like 2012 for tracking whether stuff internally in bitcoin was stolen or whatever…
“While the taint analysis tool aims at measuring the “correlation” between two addresses, there is another notion of taint in the Bitcoin community which refers to the percentage of bitcoins, that come from a known theft or scam and have been blacklisted by popular exchange markets. For example, in 2012 the bitcoin exchange Mt.Gox froze accounts of customers, who owned bitcoins that could be directly related to such an incident [20].” https://maltemoeser.de/paper/money-laundering.pdf
This wasn’t already the case?
