This is a blockchain Alliance webinar with various law enforcement officials concerning said regulations about the functionality of privacy coins, this is a good one you’re going to want to listen to the whole thing
(obviously not everything’s going to listen to all of it but the main takeaway you’ll notice is they talked mostly about Monero and how its favorited among the dark Market privacy coin sector (still fractional to btc) and how the ECC and the Zcash community were mentioned specifically when it comes to cooperation)
