The fact that you made money off it, does not make something less scammy (ie: verge, tron). While the project itself is not a scam per-se, it resorts to scammy marketing tactics. Luring in people with the idea that you're mining with your phone is a scammy tactic. Doesn't matter if you're getting credited for the fake mining, you are implying the network can be upheld securely by mobile devices (which would be awesome, imo). We all know that doesn't happen and you're basically getting some airdropped tokens. Electroneum brings literally NOTHING to the table. It is for all intents and purposes a shitcoin.
