Hey,

Does anyone here have any experience relating to bitcoin gambling and taxation in the UK? Have just received a letter saying that I'm being investigated for supposedly 'running an online business'. All the money being moved in and out of my bank account has been done through bitcoin gambling, no significant trading or anything of the sort but I'm not sure how I can prove all of this to HMRC as effectively all I have is my bitcoin wallet's transactions.

Anyone who can help would be greatly appreciated.

Thanks.
