When the first decentralised cryptocurrency, Bitcoin, was launched in 2009, the concept of cryptoassets and the underlying technology were not familiar to many people. Fast forward 11 years and, based on their research published in June 2021, the Financial Conduct Authority estimated that 1.9m adults in the UK currently owned cryptocurrencies and that 2.6m had held cryptocurrencies at some time in the year, representing 5.35% of the adult population (an increase from 3% the previous year). It is therefore increasingly likely that practitioners will need to deal with crypotasset transactions in the course of their work.
