Actually the true answer is simple - the more time you spend in crypto (trading, bounty, etc), the more you get. Dont pay much attention to those who complain about scam bounties. They just dont know how to choose correct one. Or lazy enough to choose good one.
Is it really that easy? Just spending more time in a certain thing such as bounty, trading etc doesn't always mean you'll make more money. How do you choose the "correct one"? Even the most promising bounties might end up as a failure. No guarantee how much you'll get from them. Being a trader doesn't always mean easy money as well. You have a long of rocky roads ahead of you.
