There has not been a single platform that has proven itself for long enough for this to be a recognizably safe idea in the long run. These types of things should be lock and forget, come back once per year to check and compound. Low maintenance would make it appealing for many people. But all the scams and hacks make it a bit unsafe. We will see how it develops.
Take GHO as an example. Right now, you can earn around 15% APR just for holding it. This is a limited-time offer, but it shows a bigger trend: platforms are competing for stablecoin users by offering higher yields.
15% APR is a red flag. It is either unsustainable and thus fraudulent or something will go wrong with it.
