CoinMarketCap has supported several airdrops: LUNA, KAVA, BAND, HNT, OXT, SAND and GRT.

The principle is always the same: Watch some videos (though in general not all questions can be answered with information from the videos) - take the quiz - wait till the campaign ends and get the rewards to your binance spot wallet 2 weeks afterwards.

What you need:
x) a binance account and your Binance User ID (how to find it)
Important: You have to have completed the KYC-verification before rewards can be sent.
x) an account of coinmarketcap (only email adress required)

If, contrary to expectations, you have not yet registered for Binance, please consider registering with my referral link, where you and I will each receive 10% of your transaction fees: Binance Registration with 10% reduced transaction fees

Unlike other earn programs you are allowed to take the quiz only once - in total, per Binance account and per coinmarketcap account. So please be careful while filling out the questions.
