Since the creation of bitcoin in 2009, the number of new cryptocurrencies has expanded rapidly.[1]
The UK's Financial Conduct Authority estimated there were over 20,000 different cryptocurrencies by the start of 2023, although many of these were no longer traded and would never grow to a significant size.[2]
