Since the financial promotion rules came into effect on October 8 last year, the UK's Financial Conduct Authority (FCA) has issued more than 1,000 warnings to crypto companies. Under the new rules, crypto companies must register with the FCA to promote to UK customers. Lucy Castledine, director of consumer investment at the FCA, said in an interview that these actions have resulted in 48 apps being removed from local app stores in the UK. (Coindesk)
