If someone found a way to earn steady money online, it would make sense for them to keep it to themselves. They would focus on growing their own business and would not be trying to teach strangers unless the real profit is in the teaching. Yes I believe there are ways to make money online, but I also believe 98 percent of that is a scam.
Funny thing is, the legit ones are pretty hard to find since those who know it wouldn't want to share it for competition sake.
