A wide selection of cryptocurrencies can be bought in British £ on this UK crpyto broker (not trading) platform. It is also possible to come to the London office, which in the virtual trading world is very unusual and give a higher sense of trustworthiness. You can buy currencies, but selling them requires contact with customer services and can not be done on the site. Rather slow, as they only accept bank transfers which take up to 48 hours to process. But reviewers are extremely happy with both the advice and service.
