Here's another way of earning without exerting so much effort. So how does this work?

All you gotta do is download free apps and try them out, try free games, free product trials and watch short video clips and from there, you'll get instant coins and rewards. 

When you have earned at least 2,500 coins, you can request a payout via Paypal or receive gift cards by mail.

2,500 coins = $2.5

5,000 coins = $5

10,000 coins = $10

Download Cashpirate on Playstore and sign in using my code: WVBEOS  to get instant 500 bonus coins once you sign up! Enjoy! :)

P.S. If you're worried about getting your memory full, you can uninstall apps once you received the credits. ;)
