The way to make money "easy" is to have a skill combined with an insight that most other people don't have, and work to exploit that ability for profit. For example, someone who is a good application developer but works in a dental office can identify what exactly is needed by that demographic, and how much they are willing to pay for it (thereby using their potentially "hobby" skill of programming to create that run-away successful SAAS startup).

But once you hear of other people doing something (drop-shipping items from China to Amazon, or cryptocurrency mining), chances are very good that you will have too much competition. The only way to make it big is if you get into that business before you hear of it off the street.
