What is Bitcoin and how does it work?

A cryptocurrency (also called a virtual currency or a digital currency) is a type of money that is completely virtual. It’s like an online version of cash. You can use Bitcoin to buy goods and services anonymously, but not many shops accept it yet.

All Bitcoin transactions are verified using a massive amount of computing power in a process known as “mining” as there are no physical bitcoins to hold. Bitcoin balances are maintained on a public ledger that everyone has access to (although each record is encrypted).

How does bitcoin work?

Instant payments are made possible by Bitcoin’s use of peer-to-peer (P2P) technology. Mining is the process of verifying transactions on a blockchain by independent individuals and companies who own the governing computing power (the release of new Bitcoin) and charge transaction fees in Bitcoin.

Computers that run Bitcoin’s code and store its blockchain (known as “nodes” or “miners”) make up the Bitcoin system. It is possible to think of a blockchain as a collection of blocks. These blocks contain transactions.

No one can cheat the system, as all computers are running the blockchain have the same list of transactions and blocks, and can see the new blocks being filled with the latest Bitcoin transactions transparently.

Is bitcoin secure?

It is extremely hard to duplicate, make fake, or spend bitcoins you do not own because every transaction is publically recorded. Bitcoin wallets can be lost or deleted, which will result in the loss of all Bitcoins. 

Over the past few years since the creation of Bitcoin in 2009, there have been ups and downs in its value and some people do not feel it’s safe to exchange real money for Bitcoin.

The Bank of England governor Andrew Bailey made this concern known in October 2020. 

The man pointed out that investors should be aware of the extremely volatile nature of Bitcoin price, saying he was “very nervous” about people using Bitcoin for payments.

Essentially, he meant that investors could lose money at any time if the value dropped drastically at any time.

How is Bitcoin mining possible?

Bitcoin is mined and released into circulation by the mining process. In general, mining is the process of uncovering new blocks of information in the blockchain using computationally challenging puzzles. 


Bitcoin is not physical at all, most effective balances are stored on a public ledger that everybody has obvious access to. All Bitcoin transactions are tested with the aid of using a huge quantity of computing strength through a procedure recognized as “mining.” Bitcoin isn’t issued or subsidized with the aid of using any banks or governments, neither is a man or woman bitcoin treasured as a commodity.

Bitcoin vs. Bitcoin Cash 

Transaction Speed

The time it takes the Bitcoin network to process transactions in 10 to 20 minutes. Bitcoin Cash transactions are often almost instantaneous. However, Bitcoin Cash is not used nearly as much as Bitcoin, so it has not been really tested to the same degree in terms of transaction numbers. 

Transaction Fees

One of the main criticisms of Bitcoin is its high transaction fees. Bitcoin Cash has lower average transaction fees than Bitcoin ($.0019 for Bitcoin Cash vs. $0.39 for Bitcoin).


Bitcoin and Bitcoin Cash each have their own value. Because Bitcoin Cash has addressed the scaling issues that Bitcoin faces, many people speculate that Bitcoin Cash might take over a good portion of Bitcoin’s market share. Bitcoin Cash is currently staying within the range of 10-15% of the price of Bitcoin. (Bitcoin Value


Larger blocks take up more hard drive space, which costs more for node operators. That means fewer individuals can afford to operate nodes that store the blockchain and serve it up to other users. This can lead to more centralization in the network. Mining of both Bitcoin Cash and Bitcoin is becoming increasingly centralized in mining farms with specialized hardware.


Since so far neither Bitcoin Cash nor Bitcoin blockchains have been hacked, in practice, both are just as secure. In theory, slower systems are considered safer. So, Bitcoin may be more secure, but at the cost of speed and processing power.


Bitcoin Cash’s adoption rate and market penetration are much lower than Bitcoin’s. This has a lot to do with the fact that Bitcoin Cash is much newer than Bitcoin.

Hash rate

Hash rate, or mining power, represents how much computing power miners are using to confirm transactions and secure the network. Bitcoin’s total hash rate is around 100 exahashes, while Bitcoin Cash’s is about 2 exahashes.

Is it legal to mine cryptocurrencies like Bitcoin?

The legality of Bitcoin mining depends on where your location is. The concept of Bitcoin may threaten the dominance of fiat currencies and government control over financial markets. For this reason, Bitcoin is completely illegal in some places. Owning Bitcoin and mining is legal in most countries. Some examples of places where it was illegal according to a 2018 report were Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan.8 Overall, the use and l Bitcoin mining remains legal in much of the world.

Can Bitcoin be a long-term investment?

The value of Bitcoin has been far from imagination over the past decade. In 2010, 10,000 bitcoins were exchanged for two pizzas. Today (late 2021), it is possible to buy more than 10 million pizzas with 10,000 bitcoins. At some point in 2021, bitcoin hit a record high of over $65,000. It is not known whether the value of bitcoin will continue to rise at such a rate over the next decade. 

Things like government regulations, security improvements, new second-tier technologies like the Lightning Network, and adoption rates will all play a role in shaping the bitcoin of the future. The potential of the cryptocurrency and its past performance have attracted many investors, while the risks involved have scared many. No matter what field you find yourself in, holding a fraction (if not all) of your bitcoin for the long term could pay big dividends.
