From the looks, seems the airdrop claims long elapsed which I think would not be feasible because its been a long time now when they closed the claiming entry. Looking at the pictorial excerpts, it could be said that the team long past that stage making it a tough one to do as it relates to claiming of airdrop. You should just forget about it because they longed passed that stage. If you feel that coin is a good one and worth holding, you can purchase and hold form a long term as it pleases you.
