The banks in the UK often close people's accounts for being involved in Bitcoin. If the UK plans to become the global bitcoin hub its banks will have to change their attitude to bitcoiners. Most countries banks are hostile to Bitcoin, some are more hostile than the UK banks, but almost none of them seem friendly.
Yup. It's fucking dire. No actual crypto business in their right mind would set up in Britain because of the banking situation. There are no shortage of EU banks that host accounts so they'll just bypass the UK completely.
The banks claim it's because of unclear legislation. We'll see if that changes if any's introduced. I would've thought it was more to do with the sheer hassle of having to deal with potential money laundering checks imposed by the government.
