Crypto currency trading hedge funds tracked by index provider BarclayHedge ended 2022 down almost 50%, according to a report by Reuters, with the fallout from the collapse of Sam Bankman-Fried's cryptocurrency exchange FTX still impacting the industry.

The report cites the Cryptocurrency Traders Index, an index of 47 firms – the names of which are kept secret by BarclayHedge – as having seen a loss of 47% for the year.

Despite last year's big decline though, the index has seen worse performance during the last five years, with losses topping 60% in 2018.
