Cryptocurrencies are virtual assets secured by cryptography and operate on a decentralized network powered by blockchain technology. Bitcoin has been in the news for nearly two decades now, and the questions people ask about crypto have evolved alongside it. This article answers seven of the most common ones.
What Is Cryptocurrency?
Cryptocurrency is a virtual currency secured by cryptography and operating on a decentralized network powered by blockchain technology. A blockchain is a database of transactions, organized into blocks, distributed across thousands of computers connected to the same network. That distribution is what allows for transparency and makes the data resistant to manipulation.
Because cryptocurrencies operate on a blockchain, they can’t be duplicated or double-spent. While digital assets are gradually being accepted as a payment method for goods and services, much of the interest in them still comes from trading for profit, with speculation frequently driving prices.
Cryptocurrencies are described as unregulated because they aren’t issued by a central authority like a central bank, though that’s changing quickly: major economies have spent the past two years building formal regulatory frameworks around crypto, something this piece covers in more detail later on.
Bitcoin remains the most popular cryptocurrency. Its pseudonymous creator, Satoshi Nakamoto, published the Bitcoin whitepaper on October 31, 2008, and the network itself went live in January 2009.
Ethereum, Bitcoin Cash, Tether, Dogecoin, and many others are also examples of digital assets. Every digital currency other than Bitcoin is collectively known as an altcoin. Some companies issue their own tokens, which can be used to trade specifically for goods and services that the company offers.
How Do Individuals Make Money From Cryptocurrencies?
Trading
Trading cryptocurrency means exchanging fiat currency for crypto, or one crypto for another, on platforms called exchanges. Exchanges let individuals buy coins and store them in a digital wallet. Coinbase and Binance are common examples. Traders generally aim to buy when the market is down and sell when it’s up.
Mining
Mining is the process of verifying cryptocurrency transactions and adding them to the blockchain. It involves solving complex mathematical puzzles, and the node that solves the puzzle first gets to add the next block. The miner who succeeds is rewarded with newly minted coins. The process is expensive due to the computing power and electricity it requires. Bitcoin still relies on mining today.
Staking and liquid staking
Staking is a way of verifying transactions for cryptocurrencies that use proof-of-stake instead of proof-of-work. Instead of solving computational puzzles, participants stake a number of coins for a chance to validate the next block. Investors who stake more coins for longer periods generally have better odds of being selected, and the validator who processes the transaction earns a share of the transaction fees.
The clearest example of this shift at scale is Ethereum, which moved from proof-of-work to proof-of-stake in September 2022, an event known as “the Merge.” Bitcoin still relies on mining; Ethereum, the second-largest network by market value, no longer does.
A newer variation is liquid staking, where platforms like Lido or Rocket Pool let holders stake assets such as ETH while still receiving a tradable token representing their staked position, keeping the funds usable rather than fully locked up. Restaking, popularized by protocols like EigenLayer, extends this further by letting staked assets secure additional networks simultaneously, generating extra yield on top of base staking rewards.
Yield farming
Yield farming involves using financial products on decentralized platforms to earn a return, typically by locking up tokens in exchange for rewards. It’s a high-risk, high-return strategy that requires understanding the specific platform and its risks before committing funds.
Accepting crypto as a payment method
This is particularly useful for online businesses. Accepting cryptocurrency opens the door to customers who prefer paying in digital coins, and processing crypto transactions is typically cheaper than card payments or bank transfers. Businesses that accept crypto may also choose to hold it and sell later if its value rises, adding a second potential source of income.
Participating in special events
Giveaways, token burns, buybacks, airdrops, rewards programs, and forks can all offer ways to earn additional crypto beyond simply holding or trading it.
How Can Individuals Invest in Cryptocurrencies?
Investing in crypto carries real risk, so thorough research and ideally, a conversation with a financial advisor is worth doing before committing money. Thousands of digital coins exist, and only a small fraction of them are reliable long-term holdings.
Allocate a small percentage of your portfolio to crypto
Because the crypto market runs less on fundamentals and more on speculation, sentiment, and fear of missing out, it’s generally advisable to keep crypto to a modest share of an overall portfolio. What counts as “modest” is a personal decision, but 5% to 10% is a commonly cited range.
Research and choose a digital asset
Bitcoin remains the most popular cryptocurrency, followed by Ethereum. Due to volatility, many investors also look at stablecoins, whose value is pegged to a fiat currency like the US dollar. USDT (Tether) and USDC (Circle) are the two dominant examples by market share. There’s also continued interest in DeFi protocols and NFTs, alongside a newer, fast-growing category: tokenized real-world assets, like government bonds and money market funds, issued and traded on blockchain rails.
Select a platform to buy crypto
Unlike fiat currency, crypto isn’t yet offered directly by most banks or traditional brokerages, though that’s shifting as more financial institutions add crypto trading. A range of exchanges fill that gap, some paired with their own wallets for storage. Coinbase, Binance, Gemini, eToro, and Quidax are common examples. Some exchanges support only a handful of assets; others support thousands. Choosing the right one depends on what you actually plan to trade or hold.
Store your crypto
Cryptocurrencies are typically stored in digital wallets, software that holds your private and public keys rather than the crypto itself, giving you access to your assets on the blockchain. Wallets come in several forms: online, paper, hardware, desktop, and mobile.
What Determines the Value of Cryptocurrencies?
Since no central authority sets crypto prices, a number of factors drive value instead.
Node count
Node count measures the number of active wallets on a given network. It’s a rough proxy for how widely used and decentralized that network actually is.
Rising demand and adoption
Standard supply-and-demand dynamics apply to crypto just as they do to any market, reflected in trading volume and market capitalization. Wider adoption tends to push value up over time. Bitcoin illustrates this clearly across its history: it traded for less than $1 in its earliest years, crossed $1,000 for the first time in 2013, and reached a fresh all-time high above $126,000 in October 2025, before pulling back significantly in the months that followed. Long-term adoption trends and short-term price swings can move in very different directions at the same time.
Inflation of fiat currency
When a fiat currency loses value, crypto priced against it tends to rise, since a fixed amount of crypto now converts to more of that weakened currency. This inverse relationship is part of why crypto adoption tends to be higher in countries dealing with high inflation or currency instability.
What Coins Are Worth Watching Heading Into 2027?
Rather than fixed prices, which go stale fast, here’s what’s worth knowing about each major asset’s current role. (Note: pull live prices and market caps directly from CoinMarketCap or CoinGecko at the time of publication.)
- Bitcoin (BTC) remains the largest cryptocurrency by market capitalization and the benchmark the rest of the market is measured against. It reached a fresh all-time high above $126,000 in October 2025.
- Ethereum (ETH) remains the leading smart contract platform, now running on proof-of-stake, and continues to anchor DeFi, NFTs, and a growing share of tokenized real-world assets.
- Solana (SOL) has grown into one of the most actively used networks for consumer applications, trading, and payments, known for speed and low transaction costs.
- USDT and USDC remain the two dominant stablecoins, now central to a genuine global payments use case rather than just a trading tool, a shift driven by new stablecoin regulation in the US, EU, and UK.
- XRP continues to be positioned around cross-border payments infrastructure.
- BNB remains tied to the Binance ecosystem, though Binance has faced significant regulatory scrutiny across multiple jurisdictions since 2021.
Several tokens that ranked among the largest in 2021 have since declined sharply or faded from relevance entirely. Rankings like this are a snapshot of a given moment, not a guarantee of where an asset will sit a few years later.
Is Cryptocurrency a Scam?
The crypto market runs on speculation, fear of missing out, and greed in roughly equal measure, and investors in this market are bound to either make or lose money. Thousands of crypto projects exist, and only a fraction of them are legitimate.
Two collapses since 2021 reshaped how seriously this question gets asked. In May 2022, the Terra/LUNA ecosystem, once a top-10 cryptocurrency built around an algorithmic stablecoin, collapsed within days, wiping out an estimated $40 billion in value. In November 2022, FTX, at the time one of the world’s largest crypto exchanges, collapsed after revelations that customer funds had been misused. Its founder, Sam Bankman-Fried, was convicted of fraud in November 2023 and sentenced to 25 years in prison in March 2024.

Neither collapse makes cryptocurrency itself a scam. Plenty of legitimate projects and exchanges have operated transparently for years. But both are a useful reminder that the line between “volatile investment” and “outright fraud” isn’t always obvious in real time, and that even large, seemingly credible platforms can fail catastrophically.
Common Scam Tactics to Watch For
Before regulatory clampdowns, fake initial coin offerings (ICOs) were a common scam vehicle, projects raising funds through a crowdsale, then quietly disappearing. Beyond ICO fraud, common attack methods include:
Exchange and wallet hacks: Hackers breach the email and marketing databases of wallet providers to steal user email addresses, then use those addresses to trick victims into resetting their passwords, handing over access in the process.
Social media scams: Social media helps crypto projects build visibility, but scammers exploit that same reach, creating fake accounts or hijacking popular ones to solicit funds from unsuspecting followers.
Social engineering scams: Hackers manipulate targets into revealing sensitive account information, often through phishing links that redirect to fake websites designed to harvest login details.
DeFi rug pulls: Hackers target investors chasing yield farming returns by exploiting smart contracts that lock funds. Once the contract hits a certain threshold or expiration, the hackers drain it.
Will Cryptocurrency Replace Fiat Money in the Future?
Rather than crypto replacing fiat outright, the more accurate current picture is that major economies are building regulatory frameworks that let stablecoins, dollar- and pound-pegged digital tokens, operate alongside traditional money rather than instead of it. The US passed the GENIUS Act in 2025, establishing federal stablecoin rules. The EU’s MiCA framework has governed stablecoins since mid-2024. The UK finalized its own comprehensive crypto and stablecoin rulebook in June 2026.
Central bank digital currencies have also moved from proposal to reality in several countries. Nigeria’s eNaira launched in October 2021, and other central banks have continued piloting their own versions since. El Salvador remains notable as the first country to adopt Bitcoin as legal tender.
The more realistic near-term future isn’t fiat’s extinction. It’s stablecoins and traditional money increasingly operating side by side within regulated frameworks.
In Conclusion
Cryptocurrencies remain virtual assets secured by blockchain technology, with Bitcoin still the most recognized name in the space. But the ecosystem around it, stablecoins, staking, tokenized real-world assets, and a growing web of government regulation, looks considerably more mature than it did in 2021.
Investing in crypto still requires real research, the market remains volatile, and legitimate innovation and outright fraud continue to exist side by side. What’s changed most isn’t the underlying technology. It’s how seriously governments, institutions, and everyday users now treat it.
