Revenue and Customs Brief 9: Bitcoin and other cryptocurrencies (2014)

"Gains and losses incurred on Bitcoin or other cryptocurrencies are chargeable or allowable for CGT if they accrue to an individual [...]"
But also:
"depending on the facts, a transaction may be so highly speculative that it is not taxable or any losses relievable"
In my opinion, this means that gains from regular buying and selling of bitcoin are very likely subject to CGT, and that there would have to be an additional element of risk or chance to make it more speculative in order to be exempt from CGT.
I wouldn't want to defend any other position and therefore I will be including my bitcoin gains (and potentially losses) in my CGT tax return.
More evidence of a 'stall forver' plan for brexit.
Second, given the importance of the EU to UK trade, it’s likely that almost all regulations will be harmonised with the single market going forwards anyway.
Take GDPR for example. It's protections will apply to UK citizens, just as any other EU citizen, from May 2018 until such time that a) the notice period and extension period have lapsed, b) the UK government subsequently rescinds or replaces the relevant legislation.
