2-Long term: You might say, it's ok if it crashes now, it will recover long term. But think about this, the exact moment of token release will be followed by the mining app, while it's a great marketing strategy, it will greatly increase the supply even further, on daily basis, and the more people are using the app (which they would of course, it's free money), the more ETN will enter the market on daily basis. Those tokens are even more than the ones sold during the ICO. So a downward spiral is possible still!
As far as I know, the mobile mining thing is just a simulation. Am I wrong?
