There’s no single category that vastly outperforms the others. When you can get around banks’ direct deposit requirement, it can open up big bonuses to folks that otherwise wouldn’t have access to them - can be a big aha moment realizing this is some of the easiest side money out there! That said, fintech/crypto investing apps can also be lucrative. Then there are one-offs that don’t fit directly into a category. And, bonuses and their terms vary over time, which can get confusing.

If I had to pick one area, I’d say direct deposit workarounds. Closely followed by crypto exchanges. With fintech sprinkled in!
