I've only just found out about these via an email from XAPO on "Xapo World" (
https://world.xapo.com/) - they have 4 free games for Android that let you earn BTC. I just wondered if anyone had tried them? I haven't installed any yet, I have been wondering about...
- Earnings potential
- Security risks
- Battery usage
- Advertising bombardment
(Less worried about the latter two issues if the first is good and second not a concern!)
Anyway, if anyone has tried any of these games (Space Bitcoins, Bitcoin Hunter, Wheel of Bitcoins, Bitcoin Wonder Machine) I'd appreciate your feedback.
