Bitcoin was launched in 2009 and is considered to be the first cryptocurrency. The concept of blockchain technology has been discussed for decades in academic papers, but a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" helped to launch the cryptocurrency into reality.

"There is a need for an electronic payment system based on cryptographic evidence rather than trust, which allows two interested parties to transact directly with each other without the need for a trusted third party," wrote Satoshi Nakamoto. Bitcoin Papers - An introduction to open source technology in a white paper. It has come a long way since then, is now accepted as a form of payment by companies like PayPal, Microsoft, and Whole Foods.

The price of bitcoin has risen significantly. In April 2011, the price was $ 1. In April 2021, it hit a record spot price of $ 65,000 before falling back. In early July, bitcoin was trading in a range of $ 32,000 to $ 35,000.

How does bitcoin work?

Each bitcoin (trade symbol "BTC", although "XBT" is also used) is a computer file stored in a digital wallet on a computer or smartphone. To understand how cryptocurrency works, it helps to understand these terms and some context:

Blockchain: BTC is powered by an open-source code known as the blockchain, which creates a shared public ledger. Each transaction is a "block" that is "chained" to the code, creating a permanent record of each transaction. Blockchain technology is at the heart of over 10,000 cryptocurrencies that have been followed by Bitcoin.

Private and public keys: A bitcoin wallet consists of a public key and a private key, which work together to allow the owner to initiate transactions and digitally sign them, providing proof of authorization.

Bitcoin Miners: Miners, or members of peer-to-peer platforms, independently confirm transactions using high-speed computers, usually within 10-20 minutes. Miners are paid in BTC for their efforts.

Bitcoin miners - also known as "nodes" - own high-speed computers that independently confirm each transaction and add a full "block" of transactions to an ever-growing "chain" that contains a complete, public and permanent record. . of each bitcoin transaction.

Miners are paid in bitcoins as a reward for their efforts, which encourages the decentralized network to independently verify each transaction. This independent network of miners also reduces the chance of fraud or false information being logged, as most miners must verify the authenticity of each block of data before it is added to the blockchain, in a process known as "proof of work" . is required.

How does bitcoin make money?

The value of bitcoin follows the law of supply and demand and as demand rises and falls, the price of the cryptocurrency has a lot of volatility.

Storing your bitcoins: warm wallet versus cold wallet

Bitcoins can be stored in two types of digital wallets:

Bitcoin: The Cons

Recent earnings are good news if you bought BTC in December 2018; Those who bought in 2017, when the price of bitcoin was heading towards $ 20,000, had to wait for December 2020 to recover their losses.

Hacking concerns. While proponents say the blockchain technology behind bitcoin is more secure than traditional electronic money transfers, BTC's hot wallet has been an attractive target for hackers. There have been several high-profile hacks, such as the May 2019 news that more than $ 40 million worth of bitcoin was stolen from multiple high net worth accounts on the cryptocurrency exchange Binance (the company covered the loss).

Limited (but increasing) use. In May 2019, telecom giant AT&T joined companies like, Microsoft, and Dish Network in accepting bitcoin payments. But these companies are the exception, not the rule.
