Cryptocurrency (often abbreviated as "crypto") is a new form of digital currency powered by cryptography.
The journey began in 2008 with Bitcoin. Cryptocurrencies allow you to send funds to anyone, anywhere in the world. What sets them apart from traditional banking transfers or mobile payments is their foundational principle: eliminating intermediaries.
What Are Intermediaries?
Intermediaries in financial transactions can include central authorities like banks or governments. These entities intervene between senders and receivers, monitoring and censoring transactions. They also have the power to share sensitive user data with third parties.
Cryptocurrencies change this dynamic. Transactions connect senders and receivers directly, bypassing central authorities. No one else can control your funds or dictate which services you can use. This is made possible by blockchain technology.

Blockchain Technology in Cryptocurrency
A blockchain is a decentralized ledger updated and shared across a network of computers. Each new set of transactions forms a "block"—hence the term blockchain. Most blockchains are public, allowing users to add data but not remove it.
To alter or hack the system, one would need to change data on most of the network's computers, making blockchains highly secure.
Why Is It Called Cryptocurrency?
Blockchains use cryptography to secure transactions. Similar encryption has been used in banking for years, meaning cryptocurrencies offer bank-level security.
