On October 4th, the UK's Financial Conduct Authority (FCA) announced that it will lift the ban on retail investors buying crypto trading platform notes (ETNs) since 2019 from next week, provided that the relevant products are listed and traded on a local UK investment exchange approved by the FCA. Unlike ETFs, ETNs are crypto-linked debt securities and are not backed by physical assets. It is worth noting that the FCA has not lifted the retail ban on crypto ETFs or derivatives simultaneously.
