Yes as you read in the title you can earn 20$ !!
it's Similare like coinbase when they distribute token by learing and watching videos and answer the quiz
you watch every single video ( totale 4 videos ) answer the quiz and then earn 5.04$ for each one of them
And if yourefer a friend you get ENA TOKEN Value of 10 $
it seems legit as i see they will put other videos for other coins like Celius BNB , Chainlink and of course you can earn from them
