Several sites will be offering for you to 'install and open apps' to make sometimes 100x what their other offers are paying.

Simply install BlueStacks on your PC, which is a virtual android. Go to your website of choice and click on the 'install and open' app offers, or if you are feeling industrious, the ones which require you to reach a certain level or point threshold etc.

As it's on your PC on a virtual machine you will be barely using any space and can just delete it afterwards.

Other easy earnings

Hideout.tv

ref : https://hideout.tv/viewerSignup.php?refer=142132 non ref : https://hideout.tv

This is the successor to engageme.tv and smores.tv. Simply open up 3 or so tabs of this and let it run in the background to accumulate unlimited earnings. Multiple websites to cash out on, some big and some absolutely unknown. My fav is Collectskins.

Collectskins

Ref : https://www.collectskins.com/affiliate/ref/manilpwn Non ref: https://www.collectskins.com

This is a website with multiple offer walls including Hideout.tv and minutestaff. Minutestaff allows you to quickly earn by simply going on a website and clicking a link. For instance, the highest paying offer pays 1 cent worth in Collectskin coins for simply going on a website and clicking a link. I like this website because it allows cashing out in the form of CSGO skins, Steam Gift Cards, Paypal and Bitcoin among others. Also gives out 2 free coins every 24 hours, which is worth 2 cents. Every 10 minutes there is a raffle which gives out 5 free coins worth 5 cents. Great easy earnings.

Pi network.

This is a mobile app which is still in very early alpha and is still a viable way to mine crypto. Because it is still in very early alpha getting in now is a great way to earn coin. I've only been on it for 36 hours and have well over 120 pi. It does unfortunately require a referral from an existing user. My code is : manilpwn

Pi is not on any exchanges and so the value can not be manipulated and so when it does go public it'll be a great idea to have some coin already.
