Can you really make money with DeFi?

Sure, here's a question based on the paragraph "Can you really make money with DeFi?" in a questioning tone: "So, I've been hearing a lot about DeFi lately and I'm wondering, can you really make money with it? I mean, is it just a flash in the pan or is there some legitimate opportunity here? I've seen some people talking about high yields and other incentives, but is it all too good to be true? Can you break it down for me and help me understand the real potential of making money with DeFi?
