Crypto, or cryptocurrency, is a digital currency which exists in the form of digital encrypted codes. The main thing that differs it from conventional currency management is its distributed or decentralized ledger management, where transaction records are kept.

What is Cryptocurrency?
Just like traditional currencies, crypto, or cryptocurrency, is also a currency, but it is not like traditional currency notes. It operates differently from traditional currencies. In traditional currency, we can withdraw cash, and that is physically accessible, but cryptocurrency is not physically available; it is basically digitally available.
Let us learn it with the help of an example. I have a 1-dollar note or coin in my pocket physically, so I can buy things easily from a store, and all notes or coins of that specific series are the same except for their unique number. That number helps to identify that no duplicate note or coin should exist.
Just like that, in cryptocurrency, we have digital unique codes that are encrypted (which means they are changed in such a way that no one should be able to read them, like “Crypto” can be encrypted as “Gh@l7YTRui0i”). We cannot find them physically, but we can access them digitally.
Conventionally, we have banks to store our physical currency, but crypto is not centralized like the conventional banking system. It is a decentralized currency.
How does cryptocurrency work?
To record all the transactions in cryptocurrency, a distributed public ledger called blockchain is used.
The owner of the specific currency in which you want to deal has already created some codes on the blockchain. Whenever someone finds that code, he becomes the owner of that code, and that code is called a “coin.” The process of finding that code by solving complex mathematical problems is called mining. When someone mines a code successfully, he or she becomes the owner of that code and stores that code (which has now become a coin) in a digital wallet, from which he or she can spend it. That specific code can not only be mined but can also be purchased from brokers.
Now, to spend that coin, you have to become a part of that specific blockchain so that you can do transactions. You do not need any tangible coin; you just need the code and one key or ID from where you can do the transaction.
Other Important Concepts in Cryptocurrency
Mining
The process of creating new cryptocurrency and verifying transactions is called mining. Complex mathematical problems are solved by powerful computers in the Bitcoin system. When a solution is discovered, the miner receives Bitcoin as payment, and a new block of transactions is added to the blockchain. Additionally, mining protects the network and stops fraud.
How Are Transactions Made?
When a Bitcoin transaction is made:
-
The transaction is broadcast over the network.
-
Multiple computers, referred to as nodes, validate it.
-
It is added to a block after validation.
-
A new block is added to the blockchain.
This procedure guarantees the transaction's security and transparency.
Crypto’s Ledger (Blockchain)
Blockchain is a digital ledger that records cryptocurrency transactions. All transaction records on thousands of machines are stored in a distributed database called a blockchain. Unlike conventional banking architecture, blockchain systems are decentralized and are available on thousands of PCs worldwide.
This guarantees that it is:
-
Open and honest
-
Safe
-
Hard to hack
-
Decentralized
Rise of Cryptocurrency
Cryptocurrency has gained importance from being an experiment in this niche in 2009 to reaching a $3.7 trillion global worth. Bitcoin, the most popular cryptocurrency, gained 122.5% in 2024, which shows its importance as an asset. Blockchain also helped to secure it and made its verification smooth.
What is Bitcoin?
Bitcoin is a part of cryptocurrency. As I have mentioned earlier that crypto is a currency, you can say that Bitcoin is a subtype of currency. Let us learn it with the help of an example: Currency means the mode through which we can buy and sell things, or simply, we can trade. As USD is a currency and the euro is also a currency, in the same way, Bitcoin is a currency.
But there are also many other cryptocurrencies like Ethereum. So, we can say that Bitcoin is a part of cryptocurrency, but individually, it is not the whole cryptocurrency.
Why is Bitcoin Considered a Cryptocurrency?
On the basis of cryptocurrency, the first coin launched was Bitcoin in 2009. Until today, there are more than 25,000 cryptocurrencies, or you can say coins. Firstly, Bitcoin was launched in 2009 as open-source software. Satoshi Nakamoto is known as the founder of Bitcoin. Basically, due to being the first concept implementer, most people know cryptocurrency by the name of Bitcoin.
Some Popular Cryptocurrencies
Ethereum (ETH)
It is a blockchain as well as a coin, popular for smart contracts, decentralized applications (dApps), and NFTs.
BNB (BNB)
BNB is a blockchain and also a native coin of the Binance exchange and ecosystem.
Solana (SOL)
A coin and blockchain known for speed and low transaction fees.
XRP (XRP)
A blockchain and coin popular for fast, cross-border payments.
