P2P is an application that lets you sell your internet traffic for some cash.
It's really easy to use and you can earn $5-$10 a week (or even more, depending on the amount of traffic you use).
There's other alternatives (Honeygain, IPRoyal Pawns) but P2P is the most profitable.
The min withdraw amount is $1 and you can withdraw with Crypto.
The more devices you add, the more money you earn. You can also invite referrals and you receive a 50% fee. Meaning if you invite 5 guys and they make a combined total of $20, youre payed $10. Scale this up and you get the idea.
I run this on my phone and all of my computers on a home network. If you have an unlimited data plan (which nearly everyone does on a home network, and most on a mobile hotspot), then this is beer money you arent collecting.
