From the new UK fiscal year, crypto ETNs cannot be included in mainstream ISA accounts.

Starting from the new fiscal year on April 6, UK investors will not be able to add crypto ETNs to their “Stocks and Shares ISA” tax-free accounts. The UK tax authority, HM Revenue and Customs (HMRC), currently classifies crypto ETNs only as assets eligible for the “Innovative Finance ISA,” and at present, no platforms plan to support such products. Investors who already hold crypto ETNs do not need to sell them, and HMRC stated it will continue to assess whether to adjust its policy.
