CoinMarketCap has supported several airdrops: LUNA, KAVA, BAND, HNT, OXT, GRT, CYBER, FOL, TKO, IOTX, SUSHI, POLS, FOC, MBOX, REVV and many more.
Actually there are SAND / The Sandbox, CRU / Crust Network and NFTB / NFTb.

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, the mainnet adress of the promoted token or your BSC BEP20 adress afterwards.

What you need in this case:
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)
x) a BEP20 adress for example from MetaMask on BSC

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.

Here are the lessons and the link to the quiz: https://coinmarketcap.com/earn/project/nftb 
– Lesson 1: What are NFTs and why are they important?
– Lesson 2: What is NFTb?
– Lesson 3: What is the NFTB token
– Lesson 4: Getting started with NFTb

Successful users will receive $5 of NFTb as a reward and 50 Diamonds for the CoinMarketCap loyalty rewards program additionally!

The answers on https://coinmarketcap.jotform.com/212518694319967 are  

Q1: Which blockchain is NFTb built on?

And eventually you have to submit your BSC BEP20 address.
