Cryptocurrency is a decentralized digital currency that operates on a peer-to-peer network without the need for a central authority such as a bank or government. Cryptocurrencies work on the principle of blockchain technology, which is a distributed ledger system that records all transactions in a secure, transparent, and tamper-proof way. Each transaction on the blockchain is verified by multiple nodes in the network, making it virtually impossible for anyone to manipulate the records.
If some of those words sounded a bit alien to you don't worry, we are going to explain them very soon!

Blockchain Technology
Blockchain technology is a decentralized system that allows for the secure and transparent storage and transfer of information. It is built on a distributed ledger system, which records all transactions on a network of computers, or nodes. Each node in the network has a copy of the ledger, which is constantly updated as new transactions are added to the network.
The process of adding new transactions to the blockchain is called mining. Mining involves solving complex mathematical equations using powerful computers, which creates new blocks in the blockchain. These blocks contain a set of transactions, and once a block is added to the chain, it cannot be changed.
Each block in the blockchain is linked to the previous block in the chain, creating a chain of blocks that cannot be altered or deleted. This makes the blockchain a tamper-proof and transparent record of all transactions on the network.
The security of the blockchain is ensured through a consensus mechanism, which ensures that all nodes in the network agree on the contents of the ledger. In most blockchain networks, this consensus mechanism is achieved through a process called proof-of-work or proof-of-stake.
Pros & Cons
Decentralization: Crypto transactions do not require a centralized authority or intermediary, which can increase transparency and security.
Security: Cryptocurrencies use advanced encryption techniques to secure transactions, making them difficult to hack or tamper with.
Anonymity: Cryptocurrency transactions can be conducted without revealing personal information, which can protect privacy.
Accessibility: Cryptocurrencies can be accessed by anyone with an internet connection, regardless of their location or financial status.
Potential for high returns: Some cryptocurrencies have seen significant increases in value, providing investors with the potential for high returns.
Cons
Volatility: Cryptocurrencies are highly volatile and can experience rapid fluctuations in value, which can result in significant losses for investors.
Lack of regulation: Cryptocurrencies are largely unregulated, which can make them vulnerable to fraud, hacking, and other illegal activities.
Limited acceptance: Cryptocurrencies are not yet widely accepted as a form of payment, which can limit their usefulness.
Complexity: Cryptocurrencies can be difficult to understand and use, particularly for those who are not familiar with blockchain technology.
Energy consumption: Mining cryptocurrencies can be a resource-intensive process that requires significant amounts of energy, which can have a negative impact on the environment.
