I haven't read their whitepapers either,I found out about bitwalking from the news section here
it was a year ago or so,the idea sounded nice-I wanted to lose weight and start to exercise myself
so getting paid for that was appealing
judging from the description they use POW algo but it was connected to their pedometer or activity app
i.e. you have smartphone on you,wear a fitness bracelet or a heart rate monitor or similar and you get paid when you do some phisical activity
but since there are plenty of smart guys out there it wasn't too hard to create some sort of a mechanical swinging thingy to simulate walking or exercising
also the money had to come from somewhere,most likely from all sorts of ads in the app so the coin's value was too low initially
to entice users to download and use the app
but the idea is good,its the implementation that is bad (usual)
if any brave soul here downloads and installs it and tries and then leaves his comments about it,would be greatly appreciated
actually i downloaded and am using this app right now.
it's not too bad but from what I read there's a cap to how much you can walk per day but so far have not reached that cap yet. probably am not walking far enough.
but so far there's nothing that can be exchanged for the coins. the store they mentioned is not yet released from what i know.
