Bitcoins – About, mining process, risks and much more

Bitcoins – We will cover all the essentials of bitcoins in this tutorial. Read on to learn what bitcoins are and how they can be used in everyday computer-person life.

Bitcoins: What they are

Bitcoin is a form of virtual currency.  In local currency exchanges, peers store one another’s cash.  From one computer to another, the money (bitcoins) is transferred.  “Mining” for bitcoins verifies every bitcoin transaction (transfer between computers).

Bitcoins are stored directly on your computer when you first learn about them.  Does that mean you can give yourself thousands of dollars worth of bitcoins by doing some computer hacking?  No, this is not true! Hackers cannot take advantage of the system as it is designed so well.  Since bitcoins are sent from one computer to another, they must be verified to be transferred.  Mining is the process by which everyday people like you and me download some software onto their computers. This software is difficult to understand, but it performs high-level computation to verify bitcoin transfers.

In January 2009, Bitcoin was created as a form of digital currency. It is based on ideas presented by the mysterious and pseudonymous Satoshi Nakamoto.1 Whoever created this technology remains unknown. It has lower transaction fees than traditional payment methods, which governments decentralized regulate.

The Bitcoin System

Blockchains can be seen as collections of blocks metaphorically. It is a system of computers that run bitcoin’s code and store its blockchain (also called “nodes” or “miners”). There are several transactions in a partnership. No one can cheat the system because all computers running the blockchain have the same list of blocks and commerce and can transparently see the new alliances being filled with bitcoin transactions.

Whether or not a bitcoin “node” is running, anyone can observe real-time bitcoin transactions. It would take 51% of bitcoin’s computing power for a bad actor to commit a nefarious act. A Bitcoin attack seems unlikely now that bitcoin has about 10,000 nodes, as of June 2021.

If there were to be an attack on bitcoin, bitcoin miners – the people who contribute to the network by using their computers – would fork to a new blockchain so that the bad actor would be left with no reward for his efforts.

Using the algorithm used in their creation, bitcoin tokens’ balances are kept using public and private “keys,” a string of numbers and letters. Bitcoin addresses and public keys (similar to bank account numbers) are published for everyone to see.

Private keys (similar to ATM PINs) are intended to be guarded secrets and kept secret. Wallets are physical or digital devices that facilitate Bitcoin trading and can track ownership of coins. Bitcoin keys should not be confused with wallets. Since bitcoin is decentralized and never stored “in” a wallet, its term is misleading; bitcoin’s decentralization means it is stored on its blockchain rather than in a wallet.

Technology-based on peer-to-peer sharing

One of the earliest digital currencies to use a peer-to-peer payment system is Bitcoin.

Bitcoin “miners” are independent individuals and companies responsible for processing the bitcoin blockchain transaction and are rewarded with bitcoins (the creation of new bitcoin) and paid with bitcoin transaction fees.

As decentralized authorities, bitcoin miners ensure that the network is credible. The rate at which new bitcoins are released to miners is fixed but periodically declines. Bitcoin can be mined in total only by 21 million computers. By June 2021, there will be less than 3 million bitcoin left in existence.

As such, bitcoin and cryptocurrencies differ from fiat currency; in centralized banking systems, the money is released at a rate matching the number of goods produced; this system is intended to keep prices stable. According to an algorithm, a decentralized system like bitcoin sets the release rate ahead of time.

The Bitcoin mining process

To make bitcoin available to the public, it must be mined. An added block to a blockchain is found by solving computationally challenging puzzles.

Transaction records are added and verified by bitcoin mining. Mining rewards miners with bitcoins, but the reward is halved every two hundred and ten thousand blocks. In 2009, 50 new bitcoins were awarded as block rewards. The third halving of the Bitcoin reward occurred on May 11th, 2020, bringing it to 6.25 bitcoins per block discovery.


It is possible to mine bitcoin using a wide variety of hardware. Some are more rewarding than others, however. Some computer chips, called Application-Specific Integrated Circuits (ASICs), and some more advanced processors, such as Graphics Processing Units (GPUs), can accomplish more. They are called mining rigs because of their elaborate design.

The smallest unit of a bitcoin is called a Satoshi (100 millionths of a bitcoin), which is divisible to eight decimal places. Eventually, bitcoin could be subdivided to even more decimal places if necessary and if participating miners accept this change.

Satoshi Nakamoto: Who Is He?

The inventor of bitcoin is unknown, or at least we cannot be sure for sure. Satoshi Nakamoto is associated with the person or group who released the first bitcoin whitepaper in 2008 and then developed the software for the first Bitcoin in 2009. As of June 2021, many individuals claim to have been or have been suggested as the real-life people behind Satoshi; however, Satoshi’s identity (or identities) remains obscure.

It is tempting to believe the media’s spin about Satoshi Nakamoto and a solitary genius invented Bitcoin out of thin air. Still, such developments don’t happen in the absence of collaboration. Scientific discoveries are built upon prior research, regardless of how original they may seem.

In 1997, Adam Back invented Hashcash, something Wei Dai duplicated in b-money and Nick Szabo did in bit gold, and Hal Finney did in proof of work, each of which came before bitcoin. There are numerous references to Hashcash and b-money in the bitcoin whitepaper and elsewhere. Multiple people associated with the other projects listed above are suspected of having contributed to the creation of bitcoin, perhaps unsurprisingly.

Bitcoin’s inventor may have kept their identity secret for a few reasons. Despite bitcoin’s popularity-becoming a worldwide phenomenon-Satoshi Nakamoto likely would be the subject of a lot of media attention.

Bitcoin’s potential to disrupt the current financial and monetary systems could be another reason. It is possible that bitcoin could surpass nations’ fiat currencies if mass adoption of the system occurs. Taking legal action against bitcoin’s creator might motivate governments to want to protect the existing money.

In addition, there is the issue of safety. According to the block reward rate in 2009, there was a total payout of 1,624,500 bitcoin at 32,489 blocks mined. The majority of that bitcoin stash was likely possessed by Satoshi and maybe a few others through 2009.

Bitcoin is less like stocks and more like cash, where the private keys needed to authorize spending could be printed out and kept under a mattress by someone with that much bitcoin. Keeping an unknown status is probably a good strategy for Satoshi to limit exposure, even if Satoshi made any extortion-induced transfers traceable.

A Special Consideration

Bitcoin as a payment method

For products sold or services provided, Bitcoin can be accepted as payment. A sign stating “Bitcoin is Accepted Here” can be displayed on brick-and-mortar stores to encourage people to use it. Transactions are handled through QR codes and touch-screen apps, and hardware terminals. An online business can easily accept this payment option by adding bitcoin to other electronic payment options like credit cards, PayPal, etc.

Types of Risks Associated With Bitcoin Investing

Despite not being an average share investment (no shares were ever issued), Bitcoin received speculative interest in May 2011 and November 2013. Thus, bitcoin is more often purchased for its investment value than for its ability to be used to exchange goods and services.

Despite this, bitcoin purchase and use come with several risks due to its lack of guaranteed value and digital nature. Securities and Exchange Commission (SEC), Financial Industry Regulatory Authority (FINRA), Consumer Financial Protection Bureau (CFPB), and other agencies have issued numerous investor alerts.

Bitcoin is still a relatively new concept, and its credibility is still nascent compared to traditional investments. The popularity of bitcoin is reducing its experimental nature every day; still, all digital currencies remain in a developmental phase after only a decade. A bitcoin or blockchain company is pretty much the highest-risk, highest-return investment you could ever make, says Barry Silbert, the CEO of Digital Currency Group.

Regulatory Risk

It is not for risk-averse to invest money into bitcoin in any of its many forms. Bitcoin is a rival to government currency and may be used for black market transactions, money laundering, and illegal activities. The result is that governments may seek to regulate, restrict, or ban bitcoin (and some have already done so). Others are proposing various rules.

The New York Department of Financial Services, for example, has finalized regulations that require companies dealing with the buy, sell, transfer, or storage of bitcoins to record customer information and place a compliance officer on staff. It is mandatory to record and report any transaction with a value of $10,000 or more.

It is unclear whether bitcoin (and other virtual currencies) will last, be liquid, and be available to everyone.

Security Risk

Owners and users of bitcoin typically acquired their tokens through personal investments. It is far more common for them to buy and sell bitcoin on digital currency exchange, equivalent to a bitcoin exchange.

A bitcoin exchange is an entirely electronic system and, like any virtual system, is subject to hacking, malware, and operational problems. A bitcoin owner’s private encryption key could be stolen and transferred to another account if someone gained access to their computer hard drive. (Users can prevent this from happening only if they store their bitcoin on a computer that isn’t connected to the internet or use paper wallets — printing out their private keys and addresses and not keeping them on computers.)

Hackers can also gain access to bitcoin exchanges, accessing accounts and digital wallets where bitcoins are kept. Hackers stole millions of dollars worth of bitcoins from bitcoin exchange Mt. Gox in 2014, leading to Mt. Gox’s closure.

Because bitcoin transactions are permanent and irreversible, this is particularly problematic. Bitcoin transactions are similar to cash transactions: The Bitcoin recipient can only reverse the transaction by returning it to the sender. As with debit or credit cards, there is no third party or payment processor, so there is no source of protection or appeal in case something goes wrong.

Insurance Risk

Through Securities Investor Protection Corporation, some investments are insured. Up to a certain amount, bank accounts are insured by the Federal Deposit Insurance Corporation (FDIC).

Federal programs or federally sponsored insurance programs do not ensure bitcoin exchanges or bitcoin accounts. As of 2019, SFOX can provide Bitcoin investors with FDIC insurance, but only for cash-based transactions.

Fraud Risk

Scammers may sell fake bitcoin using private key encryption to verify owners and register transactions despite bitcoin using private key encryption to verify owners and register transactions. SEC actions against bitcoin-related Ponzi schemes have occurred in the past15, including a criminal case against an operator who engaged in bitcoin price manipulation, another type of fraud.

Market Risk

Bitcoin’s value fluctuates just like any investment. The currency’s value has fluctuated wildly over the short period that it has existed. The market is susceptible to newsworthy events, as volumes are high on exchanges. In 2013 the price of bitcoins fell by 61% in one day; in 2014, it decreased by 80%.
