Capital gains tax still applies though.
What is capital gains these days? I heard that it was something around £10k PA, but how is it even trackable? Is it one of those where it only matters if you take the piss with your capital gains?
Not sure. Think it's more than that. It's not really trackable, but if you sell the Bitcoins though an exchange they can track you that way.
It'll be something that 99.9999% of the time, will go unnoticed. Though if you're part of the 0.0001% that gets picked up through an exchange or by buying something with BTC, it's not going to be fun explaining to the government that you forgot to pay taxes.
