High street banks days are closing to an end

Hi guys was just wondering if there is any UK based bank that would allow you to trade large amounts on a daily basis say between £1.000 - £20.000? The reason why i ask this is because my bank account keeps getting blocked for security reasons when i'm trying to make a payment and lately i've had 3 of the high street banks closing my bank account without any reason or warning (that's what they say since there's no regulations against trading bitcoin). The website where I am currently trading has over 1 million users and has always at least around 500 active traders which actively trade without any problems and are based here in the UK. The type of trading it's P2P Bitcoin trading and not leverage trading. We can see that at a far horizon the banking system is collapsing under the weight of crypto's and to be honest i cannot be more than happy! Any suggestions on what type of bank I should use meanwhile?
