I think that today, now banking networks around the world already control all non-cash money transfers to such an extent, and competent regulatory authorities control even transfers of large amounts in cryptocurrency, that all talk and stories about money laundering are just fairy tales and fantasies for naive people. For such people who think that the mafia boss brought a bus full of bundles of dollars right to the casino doors, and let's play and "launder" these dollars. These are all fantasies from the 30s of the last century. And the times when the mafia ruled everywhere. Now it's not like that.
Cashless payments are so controlled that it is time to forget the tales of laundering some kind of criminal money and not fool people with this nonsense.
I totally disagree. Yeah, digital payments are somewhat controlled, but not in a level you seem to think. Banks are technically obligated to follow money trails etc, but most of them don't have resources to do that all the time. There are not transparent way between banks to see every transactions and most of them just rather trust the word of the customer when they ask where's the money coming from.
Money laundering still happens inside banks too today and they get caught all the time for that so not even binance or any casino is a exception to that. Regulators can't follow or control everything. That's one of the reasons cbdc is coming. To have more control over the confusing ledgers. And i am not saying casinos and exchanges would be laundering money willingly, but accidents in oversight happen and KYCs are a way to make money laundering more difficult. While not having any KYC and fiat money transactions would guarantee that people would laundering momney and avoid sanctions.
