The FCA found that 82% of people who use the products lose money, suggesting it is more akin to gambling than investing.
Of course, gambling (ex-CFD) is a legal staple of the UK economy, and whereas in Bitshares today there is no leverage provided to users, the FCA have concluded that 25x is sufficient for beginners - down from as much as 200x.
Just one more ten-fold reduction (for beginners), and they'd have a system almost as systemically robust as Bitshares.
