A way to make money when you sleep.

I think there are 3 of them:

1) The machine helps you make money. For example, to make a good software, put on the internet, as long as someone download money to register to make money, Windows is the way to get started. But this is not a typical machine to help you make money, most typical of SaaS and telecom operators. For example, you provide a service capability to the customer, as long as the server is not hanging off, this ability is always there, the customer will always enjoy your (server) services provided, you have to pay the money, so do not need your intervention, the server can help you make money.
2) financial investment to make money. Borrowed money must receive interest, this seems to have the law since the human activity, regardless of any doctrine to obey this.
3) Open the company to make money with employees. Originally this is also a good method, but this method is not suitable for the cock silk, the cost is too high, open the company has many rules and regulations.
