Will you share money making methods with the world?

[Maxwell]

I'm curious a bit If you had a really good money making method then you will share it with the world?
It can be understandable thing when someone earning well online then they would keep a really good money making method to themselves. Most people don't mind to share make money tips like email marketing, selling ebooks but really hot niches then they can keep in secret when it's good channel for making money online.

what do you think?
