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.
it's not that both of those doesn't work for everyone. it's that not everyone is willing to make the necessary effort to make both of those things work.
