As of now 78% of the total supply has been sold.
My guess is 24h remaining until none left
since this project has a good planning i think it will be less than 24 hours for this ICO to completed
It will likely go on for a few more days with the current pace the tokens are selling. Don't forget that people rushed to be the first to buy so they can get the bonuses. Now that 80% of all tokens are sold and the bonus is close to 0%, combined with the more expensive ETH and BTC it will go much slower. Still I'd be surprised if it goes on longer than a few days more.
