You guys make me laugh.... the supply is too big... where is the revenue of mining a coin that will not skyroket (x10, x 100, x1000)?
My opinion
Only 6 Billion are being sold in the crowdsale. The other 15 Billion will be mined over years. Any unsold coins are going back in to be mined as well.
The amount of coins is large on purpose and the price in the tokensale reflects that, so all the large suppy is doing, is moving the decimal point over two spots, as compared to Bitcoins 21 million. This was done so that ETN has more of a real world feel to it. So a pizza would be 12.99 ETN as opposed to .00332 BTC.
Its just a more human number.
The tokens are are still less than a cent with the 40% bonus, so 140 ETN for $1.
This is a steal when you look at who the dev is, the App already made, "First mover" advantage to successful, safe (for your phone) mining, and the plan they have.
I would read over the Overview Whitepaper or even the Technical Whitepaper if you like, and watch this interview with the dev Richard Ells
https://youtu.be/JZ8UfHG5vVw So if I understand well, may be less than 2 billion coins will be given to the early investors and you will give some 4 billion more freely to add to the 15 billion that will be dumped on the early investors.
It's not a nice way to reward your only true investors. Best way would have been to share the coins with those early investors or burn them.
2 billion coins will be bought and 19 billion given for free. I would feel cheated if I had invested in this ICO even though the price would go up by 10, because they don't show much respect to the people backing them.
