There are apps such as Sweatcoin, Stepbet, etc. That yield actual rewards that can be redeemed. The basis of these successful bussinesses is hard cash, and successful negotiations with sponsors. Actifit claims to one day be redeemable for real athletic products, but by the time this would happen (assuming for the sake of the argument that it would) AFIT will be so heavily pre mined that it would take at least tens of thousands of tokens just to equal one US dollar. Afit is not a successful token, in fact, barring any changes since I left, AFIT is not on any exchange, and it is impossible to even trade these tokens with anyone else. This begs the question, is AFIT a token, or a point? Is there an actual cryptocurrency mechanism that powers AFIT? Or is it just an entry in a ledger which is completely controlled by the actifit team? How realistic is it that someone will choose the complexity of creating a Steem account THEN setting up actifit, in order to be rewarded with nothing, as opposed to using a more reputable and established app on Google Play or the App Store which has a proven record of being rewarding? AFIT is funny money, looks fake and is fake.
