I use Gyft app to buy things I would normally buy anyway. My go to places are Starbucks, Amazon, Whole Foods etc. But I buy things using the app instead of credit card. Gyft pays me points (3% for purchases using Bitcoin).
Gyft doesn't convert points into Bitcoin directly, but I just calculate how much money I saved and I buy Bitcoins on Circle using my saved dollars. This is how I grow my own Bitcoins.
Interesting idea! but as Signature Campaign not working for everyone.
you can rent your account for signature, if you do not have enough time to post, you will earn less but i think it will still far better than faucets, especially if you have a high rank account
better to use escrow, in the case the other member want to steal you account
