How to make some money with spare Laptops or PC ?

Hello there, i have 3 laptops and 1 pc hanging around in my house and i want to use them to make some money while im at work. (i understand that this is called passive income)
Im newbie in this kind of stuff so be easy on me plzz haha

I read here that you can set up your computer to promote CPA offers on youtube
Also read about a site called FluidStack and other called Honeygain

So if you have any ideas or experience in this kind of stuff please i want to know. Tnks!!

you can get hitleap points and sell the account later

Buy a bitcoin booster from ebay, and hook it up to your old laptops to mine $100 a day easy! Even easier than the Paypal monkey generator!

You can use addmefast and similar sites to get more points by traffic exchange or likes exchange and sell those accounts.
