Since the platforms that I know where you can make money with that have been mentioned. The risk is there for all of these decentralized platforms but I'd tell you go with the ones that has high liquidity but they can also drop on an instant. And most of them, the only risk that I see with them is being attacked in the internal of these platforms but also you as a user that might someone target you and might go to the wrong website so check out the characters(letters) of their websites because some are tricky and uses special characters and you might fall for that as you connect your wallet to.
