No! Electroneum is not a scam, I already bought it and waiting for november 1 for their project. Able to mine in our mobile phones and this is great. I love their concept.
You will not mine with your mobile phone. Have you read the technical white paper?Definitely not mining but a mining experience.
Truthfully, who gives a fook if its mined or not, you will be getting free ETN anyways. I prefer to get free ETN without really mining
Cheaper.
