No coins will be used by developers that is reserved for Airdrop. As of now we have only sent around 25000 BTCU. We received more than 5000 entries. In that 50% are fake. People applying with different usernames. Even the emails they register are not valid and get bounced back! So we are in a thorough check of that. We don't want our coins in wrong hands. We haven't even shared in other forums except bitcointalk. We were busy in the development of windows wallet client 2.1 which released today as our older version was difficult for at least few people to install. The block explorer was also updated. We couldn't focus on Airdrop much. We have only advertised in Bitcointalk. From today we will begin to advertise in some other forums and consider some paid advertising too. So the airdrop will be extended to few more days. If there are any remaining coins out of the 340,000 BTCU which we had reserved for airdrop. It will be stored with a third party (may be a reputed memeber from bitcointalk) and the decision will be taken by the community. We want everything to be transparent as possible.
