I don't get it. You're trying to sell 900 million tokens during the crowd sale, right? You've sold 28 million until now. That's 3%. It seems you won't sell all 900 million before the sale ends. What will happen to the remaining tokens after the crowd sale? Will there be another crowd sale?
Available for crowdsale. Unsold tokens will be burnt automatically by the smart contract.
