Lots of posts about Electroneum lately.
I invested 2 ETH on the first day and with the 50% bonus I ended up with around 84,000 electroneum.
Right now there is a 10% bonus that ends in two days.
You can use my referral code to get an extra 1% (also I get an extra 5%).

I chose this one after extensive research and narrowing it down to three different ICO's: electroneum, cindicator, and chainlink.

My main reason for choosing electroneum is because it is trying to achieve what I sincerely hope will happen: mass adoption of crypto

Will electroneum itself have uses? Maybe, they are looking to have it used for in game currency and potentially gambling.
The success of the project is entirely dependent on how successful their mining app will be.
I believe they will be successful because the entire thing is meant to be user friendly and they are approaching it as an app that can earn enough to pay your phone bill just by using it.  A simple marketing tactic that will definitely catch on.

As far as flipping goes, I would really like to warn you that this will probably not be good for short term gains.  It's simple mathematics and economics.
However, this will definitely be a medium hold wonder.  Around 8 months to a year hold.

Of course, I have no magic crystal ball, but those are just my opinions after a loooooooooooooot of research.
