New advices please, open e business online!

Hello, I’m a digital nomad but I have my company registrer in UK since 7 years now, so I have bank account here ( barclays )
I found an article about to get e-residence in Lettonia, after get it I have to choose a virtual office service provider ( as wrote in their govern website ) , but I don’t understand who can I do with the bank…can I leave me the barclays bank ? or what do you suggest ?
