Hello guys,

I am searching an eBook to make money that doesn't contain any illegal methods and don't need investment or a small amount of money.
I don't want any saturated methods or eBay methods (buying from G2A to sell on eBay) or any kind of that methods.

Also, I don't want any site creator eBook to make money on Ads or something like that. I don't work with BTC. Also, I am Linux user if that is relevant.

I am paying on Paypal for max 20$.
