What is Cryptocurrency?

Cryptocurrency is a digital currency that relies on cryptography for security and functions autonomously without a central authority like a government or financial institution.

It enables secure and decentralized transactions through a technology called blockchain, which records all transactions across a network of computers.

How Does Cryptocurrency Work?

Cryptocurrency operates via blockchain technology, a decentralized ledger recording all transactions across a computer network.

When an individual initiates a cryptocurrency transaction, it is transmitted to nodes, computers that authenticate its validity.

Upon verification, the transaction is appended to a block, which is subsequently incorporated into the blockchain, establishing immutability and transparency.

Miners, individuals actively engaged within the network, utilize computational resources to solve intricate mathematical puzzles, thereby validating transactions and safeguarding the network's integrity.

Cryptocurrencies employ cryptographic methods to guarantee transaction security and integrity while managing the creation of new units.

25 Essential Cryptocurrency Terms

Every block within a blockchain possesses a distinct hash, serving as a cryptographic depiction of the block's contents. Any slight modification to the block's data yields an entirely different hash, facilitating the detection of tampering. 

Hashes bolster the immutability and transparency of blockchain systems, furnishing a secure means to authenticate the integrity of information across the network.

25) Pump and Dump:

Pump and dump refers to a deceitful trading tactic in which the price of a cryptocurrency is artificially raised (pumped) through organized purchasing, resulting in a temporary surge in value. Subsequently, the orchestrators sell off their assets (dump), leading to a sharp decline in price. 

This maneuver exploits unsuspecting investors who may join in during the pump, anticipating further price escalation. Pump and dump schemes are deemed fraudulent and are frequently linked with market manipulation. 

Investors are urged to exercise prudence and conduct comprehensive research to evade becoming ensnared in such orchestrated market fluctuations.


Blockchain, a decentralized ledger, underpins the cryptocurrency landscape, ensuring transparent and tamper-resistant record-keeping. Addresses serve as digital wallets, facilitating secure transactions, while mining validates and adds transactions to the blockchain. 

DeFi disrupts traditional finance by enabling peer-to-peer financial services through smart contracts. Fiat currencies contrast with cryptocurrencies, relying on government regulation. HODLing represents a long-term investment strategy, while DApps offer decentralized alternatives to traditional applications.
