What I think OP was asking for is strategies to beat the market by buying and selling at the right time. I don't have any strategies like that, and would advise against following any such "strategies."

If OP wants to take regular income from investing, the smartest thing to do is just invest in businesses that pay regular dividends. Unfortunately, those stocks are all very expensive now, but as they say, "them's the breaks." I personally only invest in crypto and don't take any income from it.
