The Financial Conduct Authority (FCA) has introduced new rules for crypto buyers in the UK, including a mandatory 24-hour 'cooling-off' period, as regulators take a closer look at cryptocurrencies following the collapse of FTX last year. The FCA has also banned 'refer-a-friend' bonuses for crypto purchases, and those promoting cryptoassets must include risk warnings in their adverts that clearly highlight the high-risk nature of investing. Under the new rules, similar to those imposed last year to reduce advertising for high-risk investments in mainstream finance, firms must ensure their advertising is not misleading.
