What are the fundamentals of cryptocurrencies?
Investors should know how cryptocurrencies operate, who generates and controls them, and why they can be a good investment.
While investing in cryptocurrencies carries many risks and comes with the potential for fraud, there may be possibilities to accumulate money.
What is cryptocurrency?
Cryptocurrencies are virtual items you can trade, buy, and use to pay for goods. Individuals and organisations make cryptocurrencies for various purposes, but they typically have a few things in common.

How do cryptocurrencies work?
Although there are countless cryptocurrencies, many of which have distinctive characteristics, they all generally function similarly. When explaining cryptos, it can be difficult to resist using some jargon, but the ideas can be relatively simple to grasp.
They use blockchain technology
The cryptocurrency's blockchain is a digital log of all the exchanges that have taken place with that cryptocurrency. Everywhere in the world, computers keep copies of the blockchain in storage. They are frequently contrasted to general ledgers, a component of traditional double-entry accounting systems in which every transaction results in a debit and credit in distinct portions of the books.
David Donovan, senior vice president of financial services of the digital consultancy company Publicis Sapient, explains that it simply "functions like a general ledger." You might start with two coins and send one to a friend. "I'm sending you one coin, I now have one coin, and you have one coin," the blockchain would indicate.
Every set of transactions is converted into a block and chained to the current ledger. People refer to blockchains as "immutable" because once a block is added, it cannot be removed or changed.
The blockchain for some cryptocurrencies is unique. There are blockchains for Bitcoin and Ethereum, for instance. However, some cryptocurrencies are created by building on top of an existing blockchain rather than from scratch.
The blockchains are decentralised
Because they are neither issued nor backed by a government, cryptocurrencies differ from fiat currencies like the US dollar. A cryptocurrency's blockchain is not under the jurisdiction of any person, organisation, or authority. Instead, they are managed by a decentralised global network of computers.
Cryptocurrencies may also be safer due to their decentralised nature. According to Donovan, "It's hack-proof because there's no one major point of failure."
But who selects the transactions that are included in each block?
Transactions are public but pseudonymous
Another distinguishing characteristic of cryptocurrencies is their decentralised nature. Since blockchains are open ledgers, everyone can access and examine the transactions that took place. They can, however, also offer some degree of anonymity.
Donovan explains, "You have a private key, which is how you start transactions, and a public key, which is how someone identifies you on the market.
Transactions on a blockchain are linked to a crypto wallet's public key, but no one is always aware of who is in charge of that wallet. Because the public key is a person's pseudonym, cryptos are frequently called pseudonymous.

How many cryptocurrencies are there?
As of December 12, 2021, there were over 8,000 distinct cryptocurrencies, with a market value of around $2.24 trillion worldwide, according to CoinMarketCap.com.
The first cryptocurrency, Bitcoin, was introduced as an alternative form of decentralised and digital money in 2009. Since then, individuals have also developed cryptocurrencies that do additional tasks or are intended for particular transactions.
According to Parisi, there are a variety of uses for cryptocurrencies. "Others help with payments, while some are utilised in gaming contexts to gain rewards in a game. Some are made for international transfers, while others are made for little payments."
Stablecoins, for instance, are a subset of cryptocurrencies that aim to maintain a constant and fixed exchange rate with another asset, such as the US dollar. Another example of a niche cryptocurrency is governance tokens. They grant token holders vote privileges in a related cryptocurrency project.
Are cryptocurrencies secure?
The blockchain technology that underpins cryptocurrencies can enhance the security of the coins and systems. The value of blockchain, according to Donovan, "has never been contested." "the configuration of the ledger system and the manner in which each transaction is documented. Additionally, it cannot be changed."
You still have to be concerned about security because Scams abound in the cryptocurrency industry. That applies to conventional financial structures and currencies as well, of course. A fraudster never asks you to pay using a gift card or wire transfer. However, several circumstances could make cryptocurrency scams particularly concerning.
One such instance is the inability to undo cryptocurrency transactions. Additionally, compared to traditional US financial services, cryptocurrencies and platforms are less regulated. Additionally, some people could feel under pressure to transmit or invest their money immediately out of concern that they won't seize an opportunity.
According to Parisi, investing in more reputable cryptocurrencies like Bitcoin or Ethereum is one method to avoid falling victim to fraud. Regardless of how you hold, send, or receive money, you could still become a victim of fraud or scams. The Bitcoin itself, however, may be trusted to be genuine.
Are cryptocurrencies a good investment?
There are numerous ways to invest in the world of cryptocurrencies, which may offer a fantastic financial opportunity.
You might purchase a coin (or several coins) and keep them, hoping their value will rise. Alternatively, you might utilise your cash on a decentralised finance (DeFi) network to lend or stake them for interest. You might also use the more conventional approach by investing in a cryptocurrency-related exchange-traded fund (ETF). Investing in projects or ancillary businesses rather than cryptocurrencies may present an opportunity.
Cryptocurrency is rapidly changing from an investing standpoint, according to Parisi. "You shouldn't invest money that you can't afford to lose. It ought to make up a negligibly small amount of your portfolio."
The bottom line
Even though investing in cryptocurrencies is a passionately contested subject, it's essential to understand what's happening to make a wise choice. You can jump in fully or dip your toe if you want to start.
Open up wallets, accounts, and trade currencies, and study more about the use cases to gain knowledge about cryptocurrency, advises Parisi. "However, proceed responsibly. The regulation of cryptocurrencies is still in its infancy."
Donovan advises creating an account with a reputable, publicly traded company like Coinbase. But, he adds, "it's really about being clever and leveraging the system to take tiny steps."
