Anyone who trades (buys/sells) or mines cryptoassets, or uses cryptoasset derivatives, needs to first consider if they are engaged in financial trading in cryptoassets (ie a business activity), rather than simply assuming they are classed as an investor and taxed under the capital gains tax regime/miscellaneous income regime.
HMRC state: "Only in exceptional circumstances would they expect individuals to buy and sell exchange tokens with such frequency, level of organisation and sophistication that the activities amount to a trade in itself."
Whether or not there is financial trading in cryptoassets is a complex area. We recommend you read our detailed guidance and consult a professional tax advisor to consider your specific circumstances.
