Hello,
I'll wade into this as well here.
My bank, Revolut, have just frozen my banking facilities including my crypto assets whilst they investigate a potential breach of AML regulations on some of the payments I made to a non-UK casino(I'm in the UK but I'm Irish!). At the moment all I know is that these transactions have appeared and are not the name of the casino but shell companies and also the name of a scam dating site called MyDate. My bank haven't gone into a lot of detail other than asking every single thing about the transactions from device used to IP address, payment popups etc. They are treating this incredibly seriously and my account may be locked out for up to 30 DAYS whilst this is happening.
DO NOT UNDER ANY CIRCUMSTANCES pay to these offshore operators with a debit or credit card is my advice. I'm told it is a direct contravention of current UK Law and falls into the AML regulations and is known as 'Transaction Masking'.
I have no idea what will happen with this now but heed my warning.
