The android mining part is what makes me feel worse about this miner, are you trying to tell us that this miner can work on an android phone using it's CPU without burning the phone up or shorting it's life span? Can you tell me more about this?
It will not. This miner is very unique, very different from other miners.
The more story telling here is that the two coins it support are unique, one of kind, crypto innovation. Nengcoin is scrypt coin, Cheetahcoin is SHA256. In both coins, ASIC rigs (scrypt or SHA256) gets 80% to 90% of rewards, CPU miners (in computer or android phones) with this miner get 10% to 20% of total rewards. GPU is not competitive, can not compete with ASIC, can not compete with CPU either.
So you see, this is not same as typical CPU miners. Not a typical coins either. In fact, for most of the time, this miner does nothing, just observe the NENG or CHTA block chain movement. It runs like a hunting Cheetah in Africa Safari. It hides from Lions, does nothing, no actions. It jumps into mining when ASICs are stuck, not able to mine. In other word, this miner mainly profit from failure or short fall of ASIC miners. I skip the details here, you can check out both coins of their Ann page for details.
The profit gets doubled if the same phone mining both coins simultaneously at same time. In terms of CPU usage, this miner uses much less CPU resource compared to Monero. I tried and I do not believe an old android phone can mine Monero with decent rewards. This is different, actually 4 core android phone mining both coins in dual mining mode can get more rewards than a dual core old PC.
I mine on my phone daily, not getting any over-heat issue so far. Of course, when I use my android phone, I do not mine, save the battery. Mine only when your phone is idle. You are not supposed to mine on your phone when you use it for daily routine.
