I'm completely on board in this project and have invested 70,000 ETN already. I put in an extra 30,000 ETN an hour or so before the 30% bonus was over, but it never went through. It took the ETH out of my wallet and confirmed the transaction, but my ETN never updated. I e-mailed the support 24 hours ago, but to no avail. Hopefully it'll be rectified. This project looks very promising. As others have mentioned, it is not going to be using the phone's processing power to mine. It'll only use that as a benchmark to allocate more or less ETN to the phone that has the app running. The main powerhouse of mining will be left to computer miners. Since 6 billion ETN is a lot, out of 21 billion+ ETN, the leftover ETN will not be destroyed, but redistributed to people who adopt the phone "mining" capabilities. I have confidence that this will go relatively viral just because people will earn more right off the get go. People will want to get the most out of it as early adopters. They will incur more ETN up until the 6 billion ETN from the token sales is all finally mined. I'm relatively new to crypto, but the amount of backlash this company is receiving could all be abolished by just reading the white paper and technical white paper. I'm pretty confident in this venture, just for the sole reason of communication and development. I'm glad to hear that Bittrex is going to be another exchange that ETN will be listed in relatively early.
