How is Stellar Lumen a bitcoin fork? both don't even share the same vision and have no relationship. Stellar's total supply is very massive. You should edit your post and input fork instead of airdrop. Hex that I know did ICO sometime ago.
This thread is about Bitcoin Airdrops. Stellar Lumen was airdropped to Bitcoin holders. I never heard of Hex ICO. It was airdropped to Bitcoin holders as well.
