Am a near-complete neophyte in HIVE (or the "oi" world, in general), but am enthused to be a part of it.
ESPECIALLY Actifit, which I see as a WONDERFUL idea. There are many sports apps in Google/Apple, yet I don't know of any that are paying me to use them.
As soon as I get a grasp of how HIVE and this blockchain system works, you can be SURE I'll be throwing my full weight behind Actifit.
