its not scam, i think it 1 of the source of mining. you can use your rig and phone to mine in Electronium. Electronium also have a lot of project coming. so i think it is now the time to buy more electronium for the future 
Please go and educate yourself. You can't mine with a rig unless 'rig' means ASIC because they made sure of that, so much for decentralised and for the people. All this weekend showed is that the daily trade volume is so bad anyone with a reasonable amount of money can manipulate the price, that's why it rocketed before the weekend and then dropped back as those people dumped leaving idiots with bags of overpriced coins.
If you paid attention, then when the BTC started to rise in price, then on the coinmarketcap the first positions were occupied by Electroneum. I think it's hard to call a scam project if it is so badly needed by someone.
Because the price was manipulated by people/entities pumping and dumping it, go look at the charts and make your own mind up... of course, any fanboy will tell you it's not that but please explain why a coin would go from 30 BTC trade per day up to 800 BTC and don't say it's Instant Payments...
