If you've been following financial or technology trends, you've probably heard various perspectives on cryptocurrency, such as Bitcoin. Some people claim that crypto tokens represent the future of global trade, while others see it as nothing more than a Ponzi scheme for those interested in making a quick buck. This article is intended as an introduction to the technological underpinnings of crypto, allowing readers to decide for themselves what to make of it.

What is Crypto?

Cryptocurrency is any digital medium of exchange that may be used to purchase goods or services. In this sense, it is comparable to the American dollars in your wallet. However, most cryptocurrencies are decentralized, meaning no central authority controls each token's value. The supply and demand market forces dictate a token's value at any given time, creating large price fluctuations relative to more traditional money systems.

Investors like this price instability because it offers highly profitable (albeit risky) investment opportunities. However, merchants often have difficulty delivering a consistent price when one Bitcoin can be worth $9,500 today but $10,500 tomorrow.

How do crypto coins work?

Most crypto coins run on blockchain technology, a decentralized public ledger that records every transaction a given currency has ever had. Transaction info is permanently stored on "blocks" that can be "chained" to produce infinite memory, allowing every token to be traced through every account it has ever been in. Blockchain is difficult to hack, as you must alter each block simultaneously to ensure they agree.

Every blockchain transaction contains three critical pieces of information: Input, Amount, and Output. The Input is the account or accounts that initially provided the tokens being transferred to the account that is now trading them away. For example, if Jace gave Cooper the five Bitcoins he's now offering to Riele, Jace's crypto account is the Input for the transaction between Cooper and Riele. All cryptocurrency accounts (commonly called wallets) are identified on the blockchain by a random string of characters that act as a username so that suspicious tokens can be traced back to their origin point. The Amount is how much money was transferred. While most traditional banking systems cannot transact less than $0.01, many cryptos support smaller amounts of money. For example, a Satoshi (or 0.00000001 Bitcoin) is the smallest Bitcoin blockchain investment amount. The Output is simply the account that receives funds.

Volunteer miners manage transaction processing, employing powerful computers to verify that every transferred token originates from the correct account. Their compensation? Brand-new tokens. This process adds new coins to the virtual economy, bypassing the need for a central authority. The system also levies variable transaction fees, which depend on the miners' workload at the exchange time.

How do you get cryptocurrencies?

Exchanges or specialized sites typically facilitate most crypto purchases. Many recommend CoinBase.io to beginners - it supports credit card account funding and includes insurance backing. Still, other sites offer better selections and lower fees. Many exchanges also have built-in wallets, making storing your purchases easy.

It's also advisable to research crypto tokens before you purchase some. There are hundreds of altcoins (any crypto token that isn't Bitcoin) to choose from, with some of the most popular including Ripple, Ethereum, and Litecoin. Ensure your chosen sources are unbiased. You wouldn't want a dubious 'expert' swaying you, seeking profit at your expense.

What differentiates one crypto token from another?

Each token has a unique blockchain, which can vary from others. For example, Ethereum's blockchain is programmable, allowing developers to add new features constantly, while Bitcoin is mainly static. Likewise, each coin has a different planned circulation. With a cap of 21 million Bitcoin in circulation at any moment, prices can skyrocket if demand intensifies significantly. Meanwhile, Ripple has a planned circulation of 100,000,000,000 XRP that limits the value of each token no matter how high the market climbs.

Some coins are even created from an older one. For instance, the Bitcoin blockchain was subjected to a hard fork on August 1, 2017, to create a spin-off called Bitcoin Cash. Bitcoin Cash transactions can be processed faster than the original Bitcoin because each block holds more data. However, faster processing means that Bitcoin Cash transactions aren't as secure as Bitcoin's. The Bitcoin community could not agree on whether this trade-off was worth it, so it was split in two to give both sides what they wanted as a compromise. Since there is no Bitcoin governing body, disagreements within the community are often resolved through these arrangements.

Are cryptocurrencies as great as their supporters claim?

Discussing the merits of virtual money is a complex topic, too intricate to tackle in this context. Digital transactions carry several potential advantages, such as improved accessibility, but the underlying technology is still experiencing growing pains that may mean it isn't ready for prime time. Hopefully, this article helped you understand the basics of what crypto is. It's up to you to decide whether to learn more about it.


Cryptocurrency isn't just digital money; it's a technical marvel. Delving into its mechanics, from blockchain foundations to encryption nuances, unveils a sophisticated, secure transactional universe. By understanding its intricate workings, we're better equipped to navigate the ever-evolving world of digital finance. So, keep exploring and stay informed.
