so thats why i telling you to be aware of such scam they are just wasting your money in shape of free Airdrop . that i will call just a trick to make us fool . so stay away from them . their twitter account is @BitcoinQuick . block and report their twitter and bitcointalk profile as well. i do not have their bitcointalk account . any member can comment and tell others about their id .
As far as I understand, GAS is just a fuel to make sure your ether transaction goes through the network fast. The network only uses the amount of gas that is needed to process the transaction and any unused gas is returned to the sender. Gas does not go to the recipient.
For example if you put 0.11 gas and the transaction only requires 0.00011 gas, the remaining 0.10989 gas is returned to you. Specifying high gas amount is only to make sure your transaction doesn't get stuck forever.
They are not taking anything from you by specifying higher gas amount. They just want to make sure your transaction goes through fast.
Correct me if anybody thinks this is not how it works.
EDIT:
I just checked their contract and here's one of the transactions someone made for the airdrop. Gas price is $0.56. Not a big deal.
