You can earn crypto currencies for watching videos and answering quiz questions on Coinbase (after sign up + ID verification). Ampleforth ($3) and CeloGold ($11) lessons are active. You may also have The Graph(GRT), NuCypher(NU), Stella(XLM), Compound(COMP) lessons if you just signed up. The Celogold requires download of the Valora app and eventually emailing someone a referral link. You can lower the amount you send, so you get to keep more of the initial Celo Gold deposit.
Coinbase Earn also requires a photo identity verification (like most Crypto exchanges) for sign up. There may also be a waitlist if you are a new. New lessons are also added from time to time. Recommend holding as mine went up four times after a year.
