What is opinion trading, and which app is best for it? Opinion trading is a new and interesting way for people to share what they think about current topics and events. It’s simple: you just give your opinion on questions related to things like sports, entertainment, news, business, and more. If your opinion turns out to be right, you earn rewards. You don’t need to be an expert—just someone who follows what’s happening around you. https://qr.ae/pAaqGh
