Earning money from social media sites like Facebook, Twitter, Instagram and Snapchat has become lot more easier nowadays. You can choose to start with one social media platform, and then expand to other relevant networks once you or your brand become popular. After your garner some popularity and reach on social networks, you can start earning through sponsored posts. You can make a meme page and get some fans. It will take some time, and you will need to have actual fans who interact with you and share your posts, rather than just purchasing likes and fans. You need to stick down on a niche and then start growing your account with relevant posts to attract fans and subscribers. You can divert the traffic from these social media platforms to your website and earn a lot of money if you have a huge fan base.
Start your own Website/Blog
There are full time bloggers who earn thousands of dollars each month. Keep in mind is that earning through blogging requires a lot of time and effort. You will not start earning immediately ,it will take time and you have to keep patience. There are websites like WordPress or Tumblr to set up a free blog. There are some websites in which you need no special editing skills you can simply select templates and type there. If you start a website you should do research on adwords which will help you get traffic to your website. Learn about SEO it will help in the long run.

Cryptocurrency (Mining and Trading)
As the prices of bitcoin are skyrocketing, finding the right time to buy them when the price falls and investing in other alternative cryptocurrencies which are at entry level & you will end up earning a lot of money. You can find most of the information online and I recommend you to do some research about cryptocurrency and blockchain before you start investing in it. Mining cryptocurrency has become more popular these days, but the cost of electricity is the main thing which a hurdle in letting you earn more money. Using Solar power to mine bitcoins can be beneficial as solar panels have a life upto 25 years and the ROI for your overall investment will be 1.5 years. As you will be using the renewable energy.( A 350 Watt panel in India costs around $180 -$200).
Use Bing
Yes you heard it right! As Google is the search engine giant making billions of dollars. So Bing wants to make its presence by giving a few amount of money to its users for using the search engine. The amount is not big but Mr.Google is not giving a single penny why not use Bing?
Use Steemit
Steemit will help you earn a few bucks (many earn pretty good amount) giving you the similar feel of using a social media platform. People are praising Steemit here but Facebook and other ad based social media platform will not back down easily they might be working to maintain their position. Like Facebook started monetization to compete with YouTube , in future even Facebook or Instagram will change so having a good influence on all these platforms is worth. It will definitely be beneficial in the long run.
If you search on the internet you will come across thousands of ways to earn which will lead you to try few and initially making you disappointed. These above mentioned methods they are legitimate and if one puts his/her efforts they'll surely get the results. It may take time but like they say "Good things come to those who wait".
