Re: Yay money laundering!
It's already difficult to move money from your bank into or out of any of the major Bitcoin etc. exchanges.
They're not stupid, they know what's coming.
When I withdrew the last dregs of my Bitcoin, I had to do so by sending it to a third-party website who sent me an Amazon voucher... well dodgy! But it worked out.
Trying to withdraw to my full-validated, only UK bank account as a UK citizen, the transactions were just automatically refused. And I remember years ago when I was trying to buy them and credit card / debit card were refused at the bank end, not the other end.
My original Bitcoins were obtained by a third-party escrow site where you give the site £50 and then someone later sends you some Bitcoin and you confirm the transaction, then they release the money. Because the people selling Bitcoins have to use dodgy third-party means and were jumping onto anything like PingIt or any new service as soon as they launched to get there before they caught onto how they were using it.
I'm not sure how people are trading in cryptocurrencies for cash, to be honest, at least in the UK. It's quite a tricky thing to do, and far from anonymous. It's entirely reliant on taking a risk on unknown, and pretty untraceable, third-parties, companies registered in the Cayman Islands, etc.
If you want to trade in crypto, do it via an investment vehicle of some kind. You still make the money, but they take all the risk. Well, most of the risk. There's still a risk that one day what they're doing will collapse because of some new money-laundering rule, but at least you stand a chance of getting some of your money back. I wouldn't invest in Bitcoin etc. directly in this day and age.
