I finally purchased some E2C. I just saw only 2% left. For those who want to invest on this project it's better to hurry up. Since only people who have a referral link can fulfill the forms and purchase E2C, you can do it using mine: https://electronicenergycoin.com/register?ref=sfi50806
It was announced that E2C can be purchased on 25 cents until 31st January. So if you'd like to invest and buy some, it's the time.
