As the sign says, this airdrop is worth $8.50. You can join in under 5 mintues. It is the usual join Telegram/follow on Twitter/like a Twitter post type of airdrop. Once again, you will need an ERC20 compatible wallet like MEW or MetaMask. The hard part is waiting for your approval email because it is a very popular and highly rated airdrop. However, you can cut and paste the referral link they give you when you submit your application form to save time.

I could not find anything in the TOS prohibiting U.S. citizens, so it looks like a green light for everyone.
