Earn crypto on Coinbase by taking a few quizzes, but first, create and a Coinbase account using my invite link: Coinbase Invite
Use my Coinbase invite link and we will each receive $10 USD when you create an account and buy or sell $100 USD or more USD.
Once you've created an account and gone through the usual account set up, click on this link to get started with learning and earning Stellar $XLM: Learn and Earn Stellar
Once you're logged into Coinbase, you'll be able to see the crypto you can learn about and earn here: https://www.coinbase.com/earn/
As of right now, July 1st, 2019, you can earn the following crypto on Coinbase's website Dai, EOS, Stellar, and BAT.
It looks like Zcash and Ox funds have been depleted for these learn and earn opportunities.
After viewing the 1-3 minute quizzes, you'll answer 1 question after each quick and get your reward after each correct answer. Don't worry if you get it wrong, you can try as many times as needed.
Enjoy learning about crypto!
