Cryptocurrency is becoming so widely adopted that everyone from car manufacturers to universities are following suit

Cryptocurrencies鈥痟ave鈥痲uickly moved beyond the point of just being a household鈥痯hrase.鈥疶hey鈥痑re鈥痭ow commonly discussed every day.鈥疍espite鈥痑ll the鈥痓uzz,鈥痬any still don鈥檛鈥痷nderstand鈥痟ow鈥痶hey work, where鈥痶hey鈥痗ame from, or how鈥痶o鈥痷se鈥痶hem.鈥疘t is still a foreign concept to many people who have used鈥痜iat鈥(fiat means government issued currency such as US Dollars or Euro)鈥痑ll of鈥痶heir lives.

This blog鈥痳eviews鈥痶he basics of cryptocurrencies鈥痶o get a better understanding of鈥痶heir鈥痯ast, present, and future, including why so many people and businesses are adopting鈥痶hem.

The origins of鈥痗rypto鈥

Bitcoin鈥痺as not鈥痶he beginning of cryptocurrency.鈥疐ar from it. It simply did not take form in a way that fueled adoption until 2008. Before this, the idea of developing encryption-secured online ledgers had been鈥痑ttempted鈥痺ith Bit Gold and B-Money, among others, none of which finished their development.

Bitcoin changed the course of crypto history in 2008 with Satoshi Nakamoto鈥檚 paper 鈥淏itcoin 鈥 A Peer to Peer Electronic Cash System.鈥 To this day, Nakamoto鈥檚 identity remains a mystery. Bitcoin mining and software first reached the public in 2009, and the first use of it (buying two鈥疨apa John鈥檚鈥痯izzas with 10,000 BTC) was in 2010.鈥疊ased on today鈥檚 Bitcoin price those two pizzas cost $470 million, the most expensive two pizzas ever sold.

More cryptocurrencies began appearing in 2011, including Litecoin. Ethereum started to grow a following in 2016, slowly developing its name as the second-biggest crypto in the space.鈥疶oday, there are more than 6,500 cryptocurrencies that you can buy. Bitcoin hit the milestone of $10,000 in 2017. Despite鈥痷ps and downs鈥痑long the way, it is consistently making new all-time highs at the time of writing.

Cryptocurrency is digital currency that relies on the blockchain, an online ledger for transaction security.

That online ledger has very strong security. The blockchain is decentralized, which adds to its security and uptime.鈥疭imply put, ledgers are鈥痵imilar to鈥痙atabases鈥痓ut they are spread across various computers. These computers that support the ledger can be anywhere in the world, provided they have an internet connection.

So how does cryptocurrency work?

1. Creating cryptocurrency

New cryptocurrency is created as a type of code. Bitcoin, the most famous and鈥痯opular,鈥痷ses an operation called mining to generate new coins. Mining is an energy-consuming method that involves miners competing to solve a complex mathematical formula first, all 100% online. The one who does so鈥痸erifies鈥痶he blocks on the blockchain and receives cryptocurrency as a reward for doing so. While it was initially possible to make a profit mining Bitcoin, that is now quite challenging鈥痵ince you need鈥痚xpensive鈥痟igh-end equipment鈥痜or mining, and such equipment consumes vast amounts of energy.

2. Managing cryptocurrency

Most cryptocurrencies are decentralized. This means鈥痭o central authority鈥痬anages them. Instead, they rely on one of several consensus systems to verify transactions.

The previously mentioned mining method is known as proof-of-work. It is responsible for not only generating new crypto,鈥痓ut also verifying transactions. There are also other methods, with proof-of-stake being a popular option.

With proof-of-stake, those who own the cryptocurrency get to verify the transactions. You have a better chance of verifying the transaction if you have more of the crypto or have held it for longer. There typically are restrictions to prevent a single person from gaining鈥痬uch鈥痗ontrol.

With so many thousands of cryptocurrencies, these are far from the only two methods of verifying or managing them. Still,鈥痶hey鈥痑re the most common.

3. Using cryptocurrency

Using cryptocurrency requires you to have a cryptocurrency wallet. It will have a public address and a private address. You can share the public address if you want to receive crypto but should never share the private address, as it lets you send crypto.

To send cryptocurrency, you use your wallet and enter the destination address of the funds in one of two ways. You can enter it in the form of an alphanumeric string or scan a QR code.

One key point is that cryptocurrency transactions are irreversible. If you accidentally send crypto to the wrong wallet, you are out of luck and cannot get the funds back.鈥疭o,鈥痗heck and double check!

4. Early adoption to mass usage鈥

One of the best ways to measure the usage volume of a cryptocurrency is by the number of confirmed transactions per day. There were just 109 in January 2009, about 85,000 by 2015, 180,000 by early 2016, and close to 400,000 at the peak in December 2017. That dropped back down to about 180,000 by June 2018, but it has been steadily climbing since then. As of January 2021, there were between 300,000 and 350,000 daily Bitcoin transactions confirmed.

Many people see cryptocurrency as the future. This comes from its numerous advantages and the various problems it solves.

顿别肠别苍迟谤补濒颈锄补迟颈辞苍鈥

Because cryptocurrencies are decentralized, they are not dependent on any central authority nor tied to any government. This frees them from potential government influences and inflation from banks.

Limited supply鈥

The lack of inflation associated with cryptocurrency is due to more than just its decentralization (instead of being government-run). It is also due to the limited supply of cryptocurrency. For example, the Fed could print more money, which would inflate the dollar. The same thing could happen with any other government-backed currency.

By contrast, Bitcoin will only ever have a maximum of 21 million coins. Not only is the supply of Bitcoin limited, but so is the release of those coins. Bitcoin mining releases a set number of Bitcoins, but that figure is halved at regular intervals. This coin release schedule means that all 21 million won鈥檛 be in circulation until 2140.

Increased security鈥

Another point in favor of cryptocurrencies is the security associated with their decentralized nature. This comes from the use of the blockchain, which also helps with security thanks to its immutability. The ledger cannot be changed, which helps prevent fraud or people manipulating the system.

罢谤补苍蝉辫补谤别苍肠测鈥

It鈥檚 another benefit鈥痶hat comes directly from鈥疌rypto鈥檚鈥痷se of the鈥痓lockchain. Anyone can view transactions on the blockchain, although you cannot tell who is involved in any transaction. This鈥痑lso鈥痟elps prevent fraud and provides a significant increase in confidence.

础苍辞苍测尘颈迟测鈥

While some critics point to the anonymity of cryptocurrency as a concern, it is actually a significant benefit. It helps crypto appeal to anyone who wants to maintain their privacy. For example, it appeals to those who don鈥檛 want others to know how much money they have.

Simple global transactions and currency exchange

Many cryptocurrencies appeal to people thanks to their ability to be used鈥痺orldwide. This has several elements to it. One is the simple convenience of paying for something in cryptocurrency when鈥痶raveling.

Another is the fact that cryptocurrency offers an affordable intermediary currency for conversions between鈥痜iats鈥(e.g.鈥疷SD or Euro). Compared to the typical transaction and conversion fees that banks charge, the fees for using crypto to convert between two fiats are negligible.

Cryptocurrency is particularly useful for international transactions in countries where foreign currency is in short supply or not easily accessible. People in those countries may find it near-impossible to trade internationally. By providing a bridge between fiat and by functioning across borders, cryptocurrency overcomes this. Simply put, it is accessible by all, regardless of their access to international fiat.

Also, the unbanked鈥(those with no bank account)鈥痗an use cryptocurrency due to the lower barriers of entry and its global reach. This gives cryptocurrency huge potential in鈥痵ocieties鈥痺here much of the population does not have a bank account and cannot get one.鈥疉cross the world there are still over 2 billion people with no bank accounts, in some nations the unbanked represent over 50% of the population!

Quick transactions鈥

In addition to expanding the reach of transactions while reducing the fees, cryptocurrencies also reduce the time involved. There is no need to wait for an intermediary to process the transaction. This is particularly evident with international transactions. Instead of having to wait days or longer for a traditional fiat transaction, crypto only requires you to wait minutes.

Available 24/7鈥

Even with online banking,鈥痑cross most countries鈥痽our transactions will only be completed on business days during business hours. By contrast, cryptocurrency is active 24/7. This means you can buy, sell, or use it at any time of the day, no matter where you are. This lets you make financial decisions鈥痑nd transactions鈥痺ithout having to worry about limited banking hours.

Like anything, cryptocurrency is not without its critics.

Not stable鈥

One of the common complaints about cryptocurrency is its lack of stability. Cryptocurrency prices are known for their volatility.

However, supporters point to the fact that prices tend to follow an upward climb over time. They also note that as adoption increases, prices will become more stable.鈥疘f you look at Bitcoin, in 2013 it was worth a bit over $100.鈥疶oday it is worth over $45,000.

Safety concerns鈥

There are a handful of safety concerns regarding cryptocurrency. Some critics say that their anonymity will attract criminals. However, the same can be said of many other technologies.

The other security concern that critics cite is the lack of protection against scams and fraud, including the fact that you cannot reverse transactions.

One more related concern is that if you lose your private key, you will not be able to access your money. This increases the risk of complete losses for forgetful people.鈥疶hankfully, this can be overcome. All you鈥痟ave to鈥痙o is store the private key and seed code somewhere secure. One option is where you put important papers, such as your birth certificate.

A new concept鈥

Some critics鈥 main argument is that adopting cryptocurrency requires a learning curve because it is a new system. Of course, this was also the case with most new concepts or technologies over the past decades.

Energy consumption

Finally, some critics point to the high energy consumption of Bitcoin mining. While this is a valid concern, few other cryptocurrencies require a similar energy consumption.

Are cryptos ready to be used as currency?鈥

Yes, cryptocurrencies are ready to be used as currency, although perhaps not on the same scale as fiat yet. The fact that more than 15,000 businesses around the world either accept Bitcoin,鈥痮r have Bitcoin ATMs on their properties,鈥痵hows that it is already in use.

More retailers and service providers are beginning to accept cryptocurrency, and the number of people with crypto wallets is expanding. Both point to widespread acceptance.

The caveat is that there are still many places where cryptocurrencies are not accepted. There is also the fact that while Bitcoin is widely accepted, many others have lower rates of acceptance in stores. However, as the demand for more places to accept crypto payments鈥痳ises,鈥痵o鈥痳etailers will have to increase acceptance.

If you want to look at the sheer numeric perspective to answer the question, you only need to look at the market volume of some of the biggest cryptocurrencies. At the time of writing, USDT-USD has the highest volume at 146.61 billion, followed by BTC-USD with 86 billion, ETH-USD at 43.91 billion, DOGE-USD at 16.75 billion, and ADA-USD at 9.27 billion.

Big businesses that already accept crypto鈥

Those 15,000 locations that accept Bitcoin are not only small local companies. Many of them are international conglomerates with thousands of locations. Looking at some of the major businesses that already accept cryptocurrency,鈥痮r plan to do so in the very near future,鈥痯rovides an idea of the adoption rate.

We鈥檒l go into a bit more detail about some, but as of early 2021,鈥痑ll of鈥痶he following accept at least one cryptocurrency. You will notice that some let you directly pay in crypto while others offer workarounds to accept it.

  • AT&T

  • Burger King

  • Expedia

  • Home Depot

  • Tesla

  • Microsoft

  • Regal Cinemas

  • Starbucks

  • Whole Foods

  • Wikipedia

In addition, PayPal鈥痑nd MasterCard鈥痑nnounced that it will be launching cryptocurrency support in 2021. This鈥痺ill鈥痓e鈥痠nitially鈥痮nly available to those in the United States, but it should expand soon. It will initially support Bitcoin, Ethereum, Bitcoin Cash, and Litecoin.

Tesla also recently announced that it will soon be accepting Bitcoin. In addition, it bought $1.5 billion worth of Bitcoin, which fueled the cryptocurrency to a new all-time high.

Influential individual investors in crypto鈥

Looking at influential people who have invested in cryptocurrency also shows the depth of its adoption. Note that we鈥檙e only listing those who are not necessarily in the crypto space. As such, Bitcoin founder Satoshi Nakamoto, Ethereum founder聽Vitalik聽Buterin, and similar figures are not included.

  • Snoop Dogg

  • Jamie Foxx

  • Bill Gates

  • Martina Hingis

  • DJ Khalid

  • Lionel Messi

  • Elon Musk

  • Gwyneth Paltrow

  • Luis Suarez

  • Serena Williams

Why businesses should accept crypto regardless of its future鈥

While many experts believe that cryptocurrency has a very strong future, there is still some debate. Regardless, it is smart for businesses to begin accepting it. This is a savvy move that helps appeal to consumers.

Essentially, there is currently consumer demand for the ability to pay using Bitcoin and other cryptocurrencies. By offering the ability to pay with crypto, companies鈥痗an鈥痚xpand their reach and appeal to their audience. With millions of people using it, accepting crypto can dramatically expand the reach of a company. This high demand is why鈥怯焉缜痙ecided to start accepting cryptocurrency鈥痠n February 2021.
