According to ChainCatcher, Warpcast reported that Ethereum founder Vitalik Buterin mentioned, "Regarding the debate over the pros and cons of prediction markets, one important point I would like to add is: most mainstream prediction markets currently do not pay interest, which makes them very unattractive for hedging purposes. This is because participation means giving up a guaranteed 4% annualized return in USD."
"I expect that once this issue is resolved, there will be a surge in hedging-related use cases, and trading volumes will further increase."
