I will pay 20% CGT - but a penny more and they will find out just what a determined bastard I can be.
I seriously doubt they'll bother asking for anything else. For them to want more you'd have to voluntarily hand over hundreds of pages nominating hundreds of trades per day. I'm sure they'll be dead pleased with the CGT windfall and leave it there.
I agree. Thankfully, HMRC isn't like the US IRS - I know them, I used to live in NYC and the IRS can get nasty.
It's likely they will accept CGT, IMO, yep. I truthfully don't know all of my trades in any case - what with Gox, Cryptsy and originally buying BTC via OK Pay to Japan etc... I just didn't have (and cannot now get) records of all purchases and certainly cannot work out all crypto trading stuff for the past five years.
But BTC bought is possible to (mostly) prove and BTC sold, I am not hiding.
It's: 'I put this in, and I have taken this out - here are my bank records'. I didn't take a penny out until this tax year anyway.
20% is not so bad, I can live with that (and it's totally honest - I have no need to hide stuff). My accountant says they can go for 'you're a trader' but I think they won't - I didn't live off it, until recently I couldn't have.
If they get shitty, I can afford a very good team of lawyers, I will be a serious pain in their rear end. I am volunteering payment, why would they bother?
