Can you lose money with DeFi?

Can you really lose money with DeFi, or is it just a rumor? I've heard about the potential for high returns, but I'm also concerned about the risks involved. How does DeFi work, and what are some of the main factors that can lead to financial losses? Is it possible to minimize the risks while still enjoying the benefits of DeFi? And if so, what steps can investors take to protect their investments? I'd love to hear your insights on this topic.
