There's many in decentralized finance. I work for a company called Balancer. On it you can invest in/create an index fund of your favorite currencies, then traders use it to arbitrage and pay you fees for doing so. So instead of having an index fund you pay someone else to maintain, you get paid for it. Or take Alchemix - You can get a loan that pays itself back over time, rather than you pay interest. Can think of it like a term deposit account where you get the payout up front instead of at the end. Or Pool Together - a no loss lottery - you can use it as a savings account which is used to generate yield, then that yield is paid out as a prize every week. Even just providing liquidity and earning a good return on that, or using something like Aave to get leverage, are things that very few people have access to in traditional finance. There's a rabbithole of super interesting innovation going on in Decentralized Finance right now that you'll never hear about from mainstream publications because it's so hard to comprehend + explain for most people. This will go mainstream over the next decade.
