so if i don't have some ether in my wallet there's no need to join an airdrop???
You can still join airdrop even if you have no ether in your wallet but you need ether to transfer your airdropped token to an exchanger.
cause a few days ago i've got some tokens and after 7 hours they went back to the sender !!!
any one explain please
thanks.
What?! Can you explain this more in detail. Can you screenshot it? Never heard of this case in airdropped token. Maybe someone had managed to access your wallet?
