Bitcoin is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network without intermediaries. Transactions are verified by network nodes through cryptography and recorded in a publicly distributed ledger called a blockchain.

When Bitcoin was launched, it started trading from $0.0008 to $0.08 per coin in 2010. Today, in 2022, the price of one Bitcoin is more than $20,000, with a total market capitalization of more than $379 billion. Bitcoin is the market leader to which altcoins oscillate due to movements.

"A lot of people automatically dismiss e-currency as a lost cause because of all the companies that failed since the 1990s. I hope it’s obvious it was only the centrally controlled nature of those systems that doomed them. I think this is the first time we’re trying a decentralized, non-trust-based system."

Bitcoin was the first cryptocurrency launched by Satoshi Nakamoto in 2009. Satoshi Nakamoto designed Bitcoin's core protocol to solve a significant issue to prevent double-spending by integrating transaction logs with blockchain technology to verify in a public distributed ledger.

Bitcoin transactions are recorded on a publicly distributed blockchain ledger, but your identity is not revealed. Bitcoin uses peer-to-peer technology for commerce, and that’s why there is no centralized authority or a central bank that manages or manipulates your transactions. Bitcoin has been gaining massive popularity because it has brought the revolution for making transactions with no centralized authority. It is the oldest digital asset, and therefore, it is widely accepted globally.

• Easy to Access: It is effortless to send money from one country to another using cash. We can buy and sell Bitcoin using online exchanges, like buying stocks online.

• Security: In Bitcoin, the peer-to-peer computer network is used that helps to secure all transactions. If a hacker wants to hack and commit fraud, he must hack many computers, which is impossible.

• Decentralization: In the stock market, New York Stock Exchange is the centralized party; in banks, the Federal Reserve and SEC (Security of Exchange Commission) has the authority to control the whole system. But, in Bitcoin, there is no individual party to own it. Instead, Bitcoin is maintained by many people in different places called miners.

• No Hidden Charges:  If you want to make an international transaction, you have to pay extra hidden costs to convert into one currency to another (US dollar to Pound). Bank takes that additional charge for making the payment successfully. But in Bitcoin, you do not have to pay such hidden transaction costs.

• Highly Profitable: As I mentioned earlier, the current price of one Bitcoin is more than $20,000. When Bitcoin had just started, the price was only $0.0008. It beats inflation, too, by a large margin. Therefore, holding Bitcoin for the long run, like 5-7 years, can create massive wealth.

• Demand and Supply: There are only 21 million Bitcoins in the market. Limited supply and higher demand mean the price of Bitcoin will keep increasing as more people choose it for their first crypto choice.

There are always opportunities in cryptography; second-gen infrastructure blockchain Ethereum is a decentralized, open-source blockchain with smart contract functionality, the second-largest cryptocurrency in market capitalization. Ethereum is similar to Bitcoin but competent to execute complex functions without using a third-party intermediary. This allows the decentralization of alternative acts in today's societies that we may see a problem to solve for the people.

Blockchain is a continuously growing list of records, called blocks linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data.

"The root problem with conventional currency is all the trust that’s required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust. Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve. We have to trust them with our privacy, trust them not to let identity thieves drain our accounts."

Blockchain technology was invented by mathematician Stuart Haber and physicist Scott Stornetta In 1991. They first started working on this technology on cryptographically secured blocks. In 1992, both men incorporated Merkle trees into a design, which would allow various types of documents to be collected in a “block.” This technology became popular after Satoshi Nakamoto integrated transaction logs with blockchain technology as the core component of Bitcoin's protocol.

Blockchain works with blocks, whereas a spreadsheet works with rows and columns. A blockchain block is a collection of data, and in the age of trust, the problem blockchain solves is that others cannot. The Blockchain has no central authority; it is the very definition of a democratized system. Since it is a shared and immutable ledger, its information is open for anyone and everyone to see.

• Speed and Efficiency: Making transactions using paper is a traditional process with chances of human error, and it sometimes requires a third party as a mediator. Therefore, it is a time-consuming process. By leveraging blockchain technology, transactions can be made faster and more effectively.

• Security: We are living in a data-driven world. It is essential to protect sensitive information. In this technology, your information is stored across a network of computers rather than a single computer or server, making it extremely difficult for hackers to view or access your data.

• Transparency: Blockchain leverages distributed ledger, which means the transactions and data are in multiple locations. The participants on the same network can access the transactions and holdings of public addresses with the help of a block explorer.

• Immutability: Once we make a transaction and it gets recorded, it cannot be changed or deleted. The record of the transaction stays permanently. Therefore, blockchain technology can be helpful to track information in the long term with a secure and reliable method.

• Tokenization: Token is when the value of a physical or digital asset gets converted into a digital token recorded and shared via Blockchain.

• Reduces Cost: Businesses can reduce massive costs associated with third-party vendors. Companies do not need to pay for a third-party vendor as blockchain technology has no centralized player. Also, less interaction is required while validating the transactions.

The public chain maintains an immutable record of transactions. Anyone can publish a transaction and participate in the network by adhering to a set of published rules. The private chain holds a shared history of transactions. The blockchain is accessible only with permission, and administrators can edit transactions. Small or large corporate businesses can use public and private blockchains to store confidential, valuable data.
