Recently, I've been looking into strange domestic economic cases and legal cases.

Summary:
1️⃣ Experts are among the people; the public has wisdom. Don't think there are only a few ways to make money.
2️⃣ Making big money often involves gray areas. Things that are prohibited are not necessarily truly harmful or even illegal. They may just touch on certain interests.
You can avoid breaking the law, but you can't be naive.
