A cryptocurrency is an entirely virtual currency accessible on the internet. In simple words, it is digital cash. The concept of digital money is abstract. We cannot touch or see this money, but we can possess it on the internet, and it carries a value of its own.

What is Bitcoin? Bitcoin is the first and most successful cryptocurrency, a form of electronic cash. It is a decentralized currency without any central authority and is generated by computers worldwide. Bitcoin is bifurcated into two segments – as the virtual coin with codes (BTC) and as a distributed protocol that records the balances of the currency, the bitcoin blockchain.

Bitcoin uses a peer-to-peer network that requires no intermediaries for its transfer. It is an open-source system with a public design.


The first-ever Bitcoin was generated in 2009 by the alias Satoshi Nakamoto who later developed the website The idea behind the protocol was to induce a means of exchange to transfer electronically in a secure and unalterable way. The mining process assists the creation of bitcoins that prove transactions and add them to the Blockchain. The mining works on the proof-of-work system where miners compete to solve the numerical code accompanying each block. The miner who does the work first is rewarded for the cryptocurrency.

The blockchain technology includes the initiation of blocks which hold particular information about a distinct trade. A block once created, becomes immutable, and the data once captured in it is unalterable. For any alterations in the previous block data, a separate block is created and attached to the initial block, thus creating a blockchain. This technology bears similarity with the ancient ledger system.

Decentralised bitcoin networkBTC network has no single administrator. The ledger system is distributed and public. The identity of users stays hidden, whereas the transactions are entirely transparent. The problem of double-spending of digital coins is solved through cryptography. Anyone can create a new bitcoin address, and anybody can become a miner. However, once a transaction is processed, it is irreversible. With no arbitrator to solve any disputes, it is impossible to modify the transaction.

What is Bitcoin Wallet and Exchange?The most prior requirement for trading bitcoin is the bitcoin wallet. A digital wallet is a program that stocks our currency and stores the secret key essential to approach the BTC address and funds. The cryptographic key is a 256-bit long number selected aimlessly at the time of wallet concoction. The wallet is a direct pathway for bitcoin transactions. Bitcoin is sold and purchased on various digital currency exchange platforms or bitcoin exchanges. These platforms help in sending and receiving bitcoins. The exchange is further added with a small transfer fee.

Buy Bitcoin

There are several ways to buy BTC.

  1. Online in exchange for fiat money. Different exchange websites permit using bank accounts, credit cards, debit cards, etc., to buy the currency.
  2. In-person – Buying BTC in cash is a unique and fast method. You can find a seller near you and trade your money for BTC. The best platform for buying bitcoin in person is
  3. Bitcoin ATM – Locate a nearby crypto ATM and exchange your cash for BTC.

Limited Supply

Unlike fiat currencies with an unlimited supply, Bitcoin asserts a limitation upon its production. The intrinsic value cash can be issued as much as the central banks want, but the fundamental algorithm tightly bottles the BTC supply. Bitcoin can be generated up to a limit of 21 million to avoid inflation in the crypto market. Besides, it adds up to the value it acquires as more demand and less supply itself ascends the rate of the coin.

Future of Bitcoin

What happens to BTC after all 21 Million are mined?

Following the limits of bitcoin generation, once all 21 million BTC are mined, the supply cannot boost, irrespective of the demand. However, satoshi, the smallest unit of bitcoin, equivalent to one hundred millionths of the currency, may still allow microtransactions, and miners would continue making profits by collecting transaction fees.
