Okay, maybe you already know about this offer, I'm posting it for those who don't. Coinbase announced on their blog that they are giving away 1 Billion Stellar Lumens. In case you don't know (again), Stellar is a Top 10 Cryptocurrency on Coinmarketcap.
This offer is available on Coinbase Earn, an initiative to educate people about Cryptocurrencies. Users watch short videos and then answer some basic questions. For every correct answer they are rewarded with Crypto. I have posted about it before, because they offer other coins too except Stellar, like Zcash, BAT and 0x.
You will get $2 for every question (there are 5 videos, so $10 total) you answer and $40 for inviting 4 friends.
Right now only people in the United States can participate and earn Stellar but it will be available soon on other countries as the company stated. If you don't live in the US, you can still get the other coins, around $16 worth of value. But don't forget to add your email to get notified when Stellar will be available for you. And BTW, you must verify your account in order to participate.
If you don't have a Coinbase account, I would appreciate if you sign up with my affiliate link.
