Hello everyone! Here is my updated list on whish CEX/platforms let you earn a small amount of cryptocurrencies via "learn" quizzes or via quests/missions.

Here the ones that I use mostly:

Binance

I do not think that Binance, the largest cryptocurrency exchange in the world, requires any presentation.

In the section "Learn & Earn" there are some videos/presentations that lead to quizzes about different crypto currencies that rewards a small amount of coins. The quizzes are quite long (5-10 questions, choosing between 4 answers each) but can be tried multiple times and also you can take screenshot during the test. The UI it's a bit "old" but it works.

Every 1-2 months new quiz are added and the old ones are removed, so remember to check this out every now and then.

Usually the amount rewarded is really small (less than 1 USD of value).

Learn and Earn is not available in all countries, there can be restrictions.

Binance requires basic KYC and an email.

CoinBase exchange

Also CoinBase requires no introduction. The exchange offers a "learn" page similar to Binance's "Learn & Earn".

Quizzes are easier and can be acccesed via app or via website. Every month new quiz are added and the old ones are removed, so remember to check this out every now and then.

The amount that can be earned is a bit greater than Biannce's (between 3 to 20 USD depending on the quiz/learn promotion).

Signing up to CoinBase requires an email and basic KYC.

Currently the "learn" quiz is about Access Protocol and the reward is 20 USD in ACS.

Learn is not available in all countries and for all users, so there can be restrictions.

CoinBase wallet (smartphone app)

This is similar to Binance and CoinBase, but it's available only in the wallet app and usually there are "quests" or "missions" instead of quizzes.

Quests are easy and requires basic stuff, such as deposit on a particular chain, mint an NFT, connect the wallet on a website etc. Every month new quests are added and the old ones are removed, so remember to check this out every now and then.

The amount that can be earned is really good (around 40 USD in 2 months of use different currencies).

Downloading and using the wallet app does not require KYC. The wallet must be active for "some time" before the quests pops up (few days or even some weeks).

Currently the quest available requires to deposit a small amount of ETH (2 USD) on Arbitrum Chainchain and you get rewarded with 15 USD in GRT.

You can do this via CoinBase CEX easily if you have some ETH available somewhere.

Revolut

Revolut it's a is a global neobank and finance tech company that offers banking services (cards, bank transfer, savings account).

Recently it also opened a "crypto" section. Thee app can be used even if you just have a free account.

The amount that you can earn the first time is good (around 10-20 USD if you sign up today). Every 1-2 months new quiz are added but usually with a lower amount of coins.

Currently these are the "learn" quizzes available:

• Polkadot;
• 1inch;
• Avalanche;
• Algorand;
• NEAR (this is the last addition, added recently).

At the end of each quiz, a small amount of crypto will be rewarded. For example, for the quiz about NEAR protocol 0,25 USD in NEAR will be rewarded.

The crypto can be immediately swapped in fiat currency and sent to you bank account via a SEPA or SWIFT transfer (please rememebr that this could be a taxable event in some countries).

Some crypto currencies can be also sent to another wallet (this feature was added by Revolut only recently). Polkadot and other few cryptos can be staked dirctly on the app.

Revolut free account requires email and basic KYC.

The quizzes are not available in all countries and there can be restrictions.

Crypto.com

Another famous exchange, You can earn 1 diamond each day for logging in. Also diamonds are awarded for various tasks (such as trading and depositing - but not worth IMHO).

25 diamonds can be traded for a random box containing CRO (usually less than 2 USD).

Crypto(dot)com account requires email and basic KYC.

YouHodler

A minor platform that is around for some years, regulated in some countries.

They offer a "BTC Miner" minigame based on the use of the app (how much you deposit, how many "MultiHodl" a user open - some kind of leverage call more or less, and other stuff).

The Minigame requires "sparks" that are earned through levels, activities or everyday. Using the spark to "mine" a "block" will rewards user with a small amount of BTC, depending on the account level, varying from 1 USD up to 30-40 USD.

Coinmarketcap earn

The famous website to track the prices off cryptocurrencies.

There is to way to earn something from the website:

• Collect Diamonds everyday, that can be swapped for rewards (discount, NFTs etc).
• a "learn and earn" section of the website that rewards an amount of a specified crypto if the quiz is done correctly. Currently there is no campaing active, but you can signup for updates via email.

​

Just a closing suggestion, when you are rewarded with a "shitcoin", remember to swap it for a major coin such as ETH or BTC. Many of the coins rewarded are highly deflationary and lose value over time! For example, I earned 15€ on Revult and never swapped the cryptos there... now the total amount it's less than 10€!

​

These are the main apps that I use to earn some free coins.

Whay do you think about it? Do you know any other Apps/CEX/Wallet that reward users in similar way?
