Requesting simple investing advice.
I'm a full-time wagecuck uni student and I want to invest my money better but I am too busy to do any focused kind of trading. Last year I put a couple thousand in a CD and made like 30 bucks over a year's period and now I'm looking for something safe like a CD but with slightly better return. i've got a couple thousand in SPY as well but that's probably as risky as I'm willing to go.
what are some other options?
is it worth learning dividends investing?
how am I supposed to know if dividend stuff is more worthwhile/safer than just putting it in a stock?
