Some of these programs go a step further by incentivizing users and rewarding them with free crypto for every piece they read and participate in. For example, CoinMarketCap has its own learn-and-earn program where users participate in crypto lessons and test their knowledge. https://devfolio.co/@JimmyWow In addition, banking apps like Revolut also incentivize their users to learn.
If you’re looking to earn free cryptocurrency, you have a number of options, from the usual suspects at brokerages and exchanges offering freebies to the unusual, such as airdrops and surveys. As you work through your free options, however, make sure you’re working with a reputable partner or it just may be them who gets your cryptocurrency for free.
Staking involves holding your cryptocurrency during a predetermined set of times in exchange for interest, similar to a savings account. This method is often used in proof-of-stake consensus protocols, where users validate transactions and receive rewards. Platforms like OKX offer ETH 2.0 staking with rewards, such as the Shanghai upgrade, allowing users to earn 4.02% in BETH.
How does cryptocurrency work
What is cryptocurrency? Cryptocurrency is best thought of as digital currency (it only exists on computers). It is transferred between peers (there is no middleman like a bank). Transactions are recorded on a digital public ledger (called a “blockchain”). Transaction data and the ledger are encrypted using cryptography (which is why it is called “crypto” “currency”). It is decentralized, meaning it is controlled by users and computer algorithms and not a central government. It is distributed, meaning the blockchain is hosted on many computers across the globe. Meanwhile, cryptocurrencies are traded on online cryptocurrency exchanges, like stock exchanges. Bitcoin (commonly traded under the symbol BTC) is one of many cryptocurrencies; other popular cryptocurrencies include “Ether (ETH)” and various altcoins that serve different purposes within the ecosystem.

The first cryptocurrency introduced was Bitcoin, the most commonly traded one. Ethereum is the second most valuable cryptocurrency and can be used for complex transactions. Other more common cryptocurrencies, called altcoins, include Cardano, Solana, Dogecoin, and XRP.

What is cryptocurrency mining
A block header acts as an identifier for each individual block, meaning each block has a unique hash. When creating a new block, miners combine the hash of the previous block with the root hash of their candidate block to generate a new block hash. They must also add an arbitrary number known as a nonce.
In the context of mining, the hash of each transaction consists of a string of numbers and letters that acts as an identifier. The transaction hash represents all the information contained in that transaction.
The root hash and the hash of the previous block cannot be changed, so miners must change the nonce value several times until a valid hash is found. In order to be considered valid, the output (block hash) must be less than a certain target value determined by the protocol. In Bitcoin mining, the block hash must start with a certain number of zeros — this is called the mining difficulty.
