Okay, so first off... Sorry for the delay, I have been testing some new apps and they all take quite some time before I can cash in and verify they're real, but I have some fun stuff on the way.
Anyhow, COIN app is pretty straightforward, you get paid to share your gps data. I can imagine you find this hideous. I tried it just for laughs and I have nothing to hide anyway.
You turn the app on, you tap auto mine and you walk around (or any other mode of transport). The only drawback is the app needs to stay on all thr time or you don't receive anything.
You can boost your earnings with games and placing Geoclaims.
The Geoclaims are best in areas with either really high population or really low population, in most small cities you will lose money rather than make money.
Overall I like the app, although I don't like the payout.
However I have been trying the free version and now that I know it's legit I am tempted to upgrade, there are several options available.
Check it out (yes it's my referral link) : https://coin.onelink.me/ePJg/7ovqbn3t
Final verdict is out till I try an upgrade, but it's legit.
