Qoinpro is more for fun and one of the most passive earning platforms. I have made a few bucks per month worth of different cryptocurrency over the past years with it. It automatically starts accruing bitcoin bits (and other cryptocurrencies) daily without having to do anything. It also gets a lot better when you get more people signed up. Each referral level increases your daily reward rate. But even without referrals increasing your daily reward, it still adds up and requires no work after it is all set up.
