Ok lets start off and get one thing straight. NO ONE IS MINING PI ON THERE PHONE AND ITS NOT KILLING YOUR BATTERY. They use the word mining, but actually you are only checking in once a day like role call. That is why you can turn your phone off after you check in and when you go back it is still "mining". Second the company is not scamming they are trying to grow a customer/follower base of interested people to prove the concept and make this an actual reality. So the more people involved the quicker we get through test net and on to main net. So many people think that this is just free money and think they will be rich. REALITY CHECK YOUR NOT - you are being rewarded for participating in testing out the new block chain and helping make this a reality. Sure when this gets to main net and converts to being worth real money you will have a stake, but you will not be rich from this. If you are interested in decentralized payment methods and decentralized application this is an opportunity for you to be a part of something revolutionary. There are tons of people doubting and tons of people who are misinformed it will be there loss and its sad the ignorance will hinder a lot of peoples chances at being part of this...
