Have you heard about Phoneum ? (#Phoneum), it's a crypto-currency (so it's decentralized) and the originality is that it is mobile ONLY. You can't access this cryptocurrency from anywhere else than the app.
This is a very ambitious project trying to reach a maximum number of person through the ease of use. Everyone has a phone, everyone can install an app. That's phoneum baseline.
With all the hype around cryptocurrency, this is a very good time to start project like this (Mobile mining, web mining, cpu mining, and so on...). Giving access to a lot of people to cryptocurrency is the best way to make this world evolve. Creating wealth through everyday objects (phone, computers, ...) without bothering the user with it is actually really smart. Don't you have a phone ? Don't you have a lot of useless app on it ? Time for you to get a new and useful one, and it will create revenue for you. What else can you ask ?
Now as far as I am concerned, I've used the beta app for a month now and it is amazing, phone is not burning haha ! Everytime I have nothing to do with my phone, I turn on mining and I just collect tokens while doing nothing.
This is still in early stages and the coins that we are mining are not very useful atm but you guys need to join before the real project begins !
