I think that you are wrong if you think that eletroneum is a scam. I agree that many new ICOs are turning out to be just a scam at the end. But not all. In case of electroneum, it is not a scam for 100 percent sure. It has already been enlisted on exchanges and is being traded. Its current price is $0.007392. You can also download app and mine the coin.
https://coinmarketcap.com/currencies/electroneum/No one said it was a scam - well, I didn't anyway. I don't even think Electroneum are malicious, just that they are colossally inept. Being traded and on exchanges meant literally nothing. And price-wise, it's just about at an all time low - buy signal for some of you, a warning for others.
The app is an airdrop - stop calling it mining, it's a 'mining experience' at best.
