1 - Survey Sites

Survey sites are always a little bit shady. However, I've done a lot of digging around, and have found several which really work, and give surprisingly high payouts. The first site I would recommend is CashCrate. This site allows you to do a great variety of things such as completing surveys or offers, watching videos, or even listening to the radio. In my first month there I made $50, and am continuing to earn with little effort. You also get a small cash bonus just for verifying your email.

The second site I would recommend is SwagBucks. Despite this site's silly name, it has a ton of opportunity for getting points, which can later be cashed for gift cards, or PayPal cash. Most of the tasks are simple, and even include simply using their search engine for whatever you like! 

2 - Bitcoin and Cryptocurrencies

If you've not heard of Bitcoin you must have been really living under a rock. Of course, the main news withBitcoin (BTC) is that it has skyrocketed in value. Fortunately, earning some is very simple, and doesn't require and personal investment in terms of computer hardware. The first site I would recommend is CEX.io. In essence, this site allows you to rent out processing power, which mines for BTC for you, without any other action required. The main downfall to this site is that it requires that you already have BTC to start.

Fortunately, there are sites which help you earn free Bitcoin too! The best I've found is LandOfBitcoin, which is a site that helps you to accumulate as much Bitcoin as possible from free "faucets" which trade your ad traffic for raw Bitcoin payment. Earning is simple as typing in a captcha, and this site helps keep it all organized for you, all for free! Once you've earned enough, you can get a Bitcoin wallet at CoinBase, which will allow you to store your coins, and exchange them for your local government currency.

3 - Content production

The internet is hungry for content, that's a simple fact. Fortunately there are many places where anyone can contribute theirs, and off of it makes a 100% profit margin. The first site I would recommend is Triond.com. Triond is a basic content production site where writers are encouraged to write articles about anything they want, and in return get a cut of the ad revenue for their content. This site is great for people who are wanting to commit maybe a half hour to an hour a day, and still make some bonus cash.

The second site I would suggest is Smashwords. Smashwords is an amazingly brilliant site which allows writers of any genre (fiction, nonfiction, historical, sci-fi, you name it) to get their e-books or short stories published with all of the major ebook vendors out there, examples include Apple, Sony, Barnes and Noble, and many more vendors. Not only is this a great way to build a writer's portfolio, but with the option to make your own price, and up to 70% royalties, it's a fantastic way to make money.
