I had friend who downloaded a mining application from his tablet. I am just confuse if is it legit or not? If not, is possible in some ways? How?
Thank you guys for your ideas.
You are missing a few key points.
1) Are they saying they are using your phones power to mine?
2) Are they selling cloud mining?
3) Is it just a game?
If 1 is the answer then it is a lie. This does not exist yet.
If 2 is the answer then it is most likely a scam. (even reputable companies in the past turned out to be scams) Just be careful
If 3 is the answer then it probably is legit.
