I think this far off. If you have not read the white paper and what they intend to do you get hung up thinking its going to tank with the rest of ico's. I as well as many others do not see that happening. The mobile "miner" is the experience of mining yes.....thats the marketing tool, not a mining critical piece of ETN its a marketing Piece!
Imagine all the people who have access to wifi with their cell phones, yet not a general decently powerful computer. So yes the blockchain is run on everyones computers while the mobile miner is just giving away free coins. If you look they have security measures for the mobile mining as well. A simple one would be "get the best phones on the market, test their hash rate, anyone who is above the average high hash rating would be flagged, so no such "quantum" phone would then get all coins or large amount ect. Quantum computers do not work in this function anyway, Non of the styles I know about anyway and I do try and stay a little up to date on current quantum setups.

Not to mention ETN will be creating miners for XBOX and Playstation. How many consoles are out there?
ETN will also make It tradable with in game money like world of war craft where in game items are sold for out of game real money. The ETN would make this a more safe, cleaner environment for that to happen.

The mobile miner will not last for forever but if you give people free coins, they will likeyl put their own money in as well, If ETN is their first crypto to own, It may very well be only traded for other cryptos, they will most likely be putting in their own money into crypto as well after first learning about it. That is what all people do when they learn about it right?

Its like JOBY WEEKS, despite how you feel about him he walks around asking people if they have bitcoin, if they say no he offers to give them 5$ in bitcoin and set them up a wallet.
How many of those people that he gave 5$ away to just took it and ran?
How many took that 5$ and then invested with his company bitconnect club?
How many people can you give away 5$ to when one big person signs up?

I think your a little to scared of this and need to look further. I as well as many local friends believe in this coin as full as ether.
