Coinbase is the famous online platform for buying, selling, transferring, and storing digital currency.
It also offers a learning platform, Coinbase Earn, where you can watch videos about different assets and learn how they work, the philosophy and the technology behind them.
This is very useful when deciding to invest on them and understanding if they are based on a solid concept, because this could tell you if they will survive, and hopefully gain value, in the long term.
Even better, the platform lets you answer a simple question about the video; with a correct answer you will earn a small amount of that coin.
Some coins also have a referral program: invite other friends (usually up to 4) to join the learning platform, and you can earn even more coins.
Unfortunatly, you can't immediatly start earning: after applying to the program, you'll be added to a waitlist, and then informed with an e-mail as soon as you're eligible to start earning. I don't know the conditions to be considered eligible, because it seems pretty random, but the sooner you enter the wishlist, the more chances you have to be chosen.
This is the current list of available coins (at least here in Italy, maybe in other countries it could be different):
3 lessons, $6 in CELO
3 lessons, $6 in KNC
3 lessons, $9 in COMP
3 lessons + 4 referral invites, $10 for each invite
3 lessons, $6 in XTZ
3 lessons, $6 in DAI
5 lessons, $10 in EOS + 4 referral invites, $10 for each invite
5 lessons, $10 in XLM + 4 referral invites, $10 for each invite
3 lessons, $3 in ZEC
3 lessons, $3 in BAT + $7 if you install Brave browser
3 lessons, $3 in ZRX
Referral invites allow you to jump the waitlist and start earning, so you can send them to your friends and they can easily earn too.
Here are a couple of invites I still have available, in case you're interested in earning these assets:
Stellar Lumens, 3 invites still available:
Eos, 4 invites still available:
The earned coins will be automatically added to your Coinbase wallet, so you can decide to convert them to other assets, or send them to your personal wallet.
Of course we're not talking about big figures, but if you sum all these earnings it could be a good starting point to collect and own some different cryptocurrencies and maybe the next big thing is among them!
