If it is mining as in mining, that is not going to last long. If a CPU overheats and consumes a lot of electric energy, then a cell phone will have a shorter battery or life span. Think twice about this. You might end up buying a new cell phone every month.
Very well said. Mining uses a huge amount of energy and I don't think that phones can handle this kind of activity. If you want to mine then buy a mining rig because I phones can nothing to do with it. Besides, there will be halving again you need to upgrade your mining rig in order to solve those blocks. And even a computer I think would not be a good idea to use upon mining so better if you will purchase a mining rig.
it is a social mining, as I understood, it is not PoW, so does not require a lot of processing power, it is important to have many contacts to reach larger rewards...
app goal is to have trusted network, through people include people they trust in a secure network, but since there is a better reward if you introduce more people, people are willing to introduce everyone, and main goal to have secure and trusted network will not be easy to reach...
it is not trade-able, as far as I know
