Wu said that Ethereum founder Vitalik Buterin stated on Farcaster that an important point he wants to add to the debate about the pros and cons of prediction markets is: most mainstream prediction markets currently do not offer interest, which makes them very unattractive for hedging, because just by participating, one is equivalent to giving up the 4% annual yield that could be earned in USD. He expects that once this issue is resolved, a large number of hedging application scenarios will be opened up, and trading volume will significantly increase as well.
