Who it affects
Anyone who holds or trades cryptoassets.
What you should do
Get your records and any capital gains in order now, before the data reaches HMRC. Work out your gains across disposals, including crypto to crypto trades.
Crypto is firmly on HMRC's radar. Sorting your position now is far easier than responding to a query later.
