tested it and yes you're right. it's not wasting time to run it but it does screw up our battery and i think this kind of app can make my windows phone gone dead very very super quicker. trying this apps is wasting time for sure because we will hate that apps later after we tried it. just like you said, leave it, never think about that anymore. that mining job will never be possible for any kind of phone.

we can do airdrop, register and referring other people to the newcomer altcoin/ico, just like i've been doing right now.

i think for the beginner like us, just don't think about signature campaign first. let's just do some airdrop job, and when our rank is up to the minimum jr.member then we newbie can start to think and search the best and latest signature campaign.
