It's too early to judge them, although they are not living up to our expectation this is the most hype coin last year and one of the most successful ICO too, but no Ico investors have lost here yet because at the current price it's the Ico price, and remember you have a bonus plus a referral earnings as well, let's wait a few more months.

It's not a scam, the use of mobile phones for mining could be absolutely revolutionary for crypto if it is done properly, it would bring so many people in to the market who are interested in gaining some passive income.
Except it's not done properly, it's fully centralised, controlled by the dev team who can't barely pull a functional app out their backsides. And then to add insult to injury, they've allowed ASICs back on the network which shuts out GPU miners and is another step away from decentralisation.
The hash power was TOO CENTRALIZED without the ASICs that why they switched back.
