Cointiply is a site to earn free crypto. It is the easiest one I have found to earn money on. I go on the site passively and get about $5.00 of Bitcoin a month, but if you more actively complete surveys and offers you can get a lot more. 

There are multiple ways to earn. Which include:

• Faucet (can claim every hour. easiest way to earn.)
• Rain pool chat
• PTC ads
• Surveys
• Offers
• Watch videos
• Games for mobile (get about 1,000 coins every 15 minutes)
• Interest (when you have over 35,000 coins.

Currently you can earn Bitcoin (withdraw at 50,000 points; $5), or Doge, Dash, and LTC (withdraw at 30,000 points; $3)
