The Central Bank of England is Warning Against Crypto despite Allowing Banks to Launder Hundreds of Billions of Dollars each Year

The Bank of England is now warning financial institutions from adopting or even handling Crypto, claiming that Crypto might be a threat to the financial system

If Crypto is such problematic, why does this central bank "allow" (they could do much more to prevent it) bankers to launder hundreds of billions of dollars each year?

UK’s National Crime Agency: “We assess that hundreds of billions of US dollars of criminal money almost certainly continue to be laundered through UK banks, including their subsidiaries, each year.

“The scale of the laundering, despite the UK’s leading role in developing international standards to tackle it, is a strategic threat to the UK’s economy and reputation.

“The banking sector continues to be the biggest producer of suspicious activity reports.”

This was said in 2016, what has changed? Nothing
