Cryptocurrency has surged into the global spotlight, capturing attention from tech visionaries to mainstream consumers. From Elon Musk’s cryptic tweets to Super Bowl ads and the renaming of Los Angeles’ Staples Center to Crypto.com Arena, digital currencies are no longer fringe—they’re front and center in the evolution of the internet.
This momentum is propelling us toward Web3, a decentralized vision of the internet built on blockchain technology, crypto wallets, non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs). But as we accelerate forward, it's crucial to pause and reflect: How did we get here? And what does this mean for businesses and individuals navigating this new digital frontier?
To unpack the origins of cryptocurrency, examine its current challenges, and explore its role in shaping Web3, I spoke with Jeff John Roberts, tech journalist and author of Kings of Crypto: One Startup’s Quest to Take Cryptocurrency out of Silicon Valley and onto Wall Street, as well as executive editor at Decrypt. The following conversation has been edited for clarity.
What Exactly Is Cryptocurrency?
Q: When people hear “cryptocurrency,” they often think of Bitcoin, Dogecoin, or Ethereum. But the term encompasses much more. Can you define cryptocurrency broadly—and explain why it matters now?
Cryptocurrency is a broad, often ambiguous term. At its core, it refers to software that runs on a blockchain—a digital ledger that records every transaction. Blockchains are tamper-proof, decentralized, and immutable. While these may sound like buzzwords, they describe a system where the same program runs across multiple computers, each verifying the accuracy of transactions.
Bitcoin was the first and remains the most well-known blockchain. It exemplifies these traits perfectly: a secure, decentralized ledger tracking who sent what to whom. Its enduring legacy lies in proving blockchain’s viability—Bitcoin has never been hacked and continues to serve as a benchmark for trust in decentralized systems.
Today, thousands of blockchains exist, varying widely in quality and security. Bitcoin stands out not just because it came first, but because it demonstrated that decentralized digital money could actually work.
How Many Cryptocurrencies Exist?
Q: Is there a definitive number of cryptocurrencies in circulation?
There are thousands—many of which are unreliable or outright scams with little technological value. Yet the space attracts massive speculation. Launch a new coin, and someone will buy it. This speculative nature underscores both the opportunity and risk inherent in the ecosystem.

The Origins of Cryptocurrency
Q: Where did cryptocurrency come from?
Its roots trace back to the cypherpunk movement of the 1980s—a group of privacy-focused cryptographers and programmers in the San Francisco Bay Area. They envisioned a new form of money independent of central banks, governments, or intermediaries.
Their dream materialized in 2008 with the publication of the Bitcoin whitepaper—an anonymous proposal for a secure, decentralized currency that required no trusted third party. This marked the first practical application of blockchain technology.
Was Bitcoin the First Blockchain Application?
Yes. Bitcoin proved that decentralized digital currency could function securely and reliably. Today, developers use blockchain as an operating system for more than just payments—from NFTs to smart contracts and decentralized finance (DeFi).
Who Invented Blockchain Technology?
The identity of Bitcoin’s creator—known only by the pseudonym Satoshi Nakamoto—remains unknown. In crypto circles, speculating about Satoshi is almost taboo. But evidence suggests it may have been a collective effort involving early Bay Area programmers like Hal Finney and Nick Szabo. Even if they weren’t Satoshi, their contributions were vital to Bitcoin’s success.
Q: So Satoshi is like a mix between Benjamin Franklin and Banksy?
Exactly—a brilliant analogy.
Who Governs the Cryptocurrency Ecosystem?
Q: With billions of dollars in circulation, who oversees this system?
Many in crypto will say it’s fully decentralized—no leaders, no banks, no authority. But every project needs some form of leadership. Even Bitcoin, the most decentralized blockchain, relies on a core group of developers who maintain and update its code.
Like any software—iOS or Chrome—blockchains require updates. These are usually small patches for security or performance. While the core team protects Bitcoin, they don’t control it outright.
Other blockchains are less decentralized. Some are dominated by individuals or groups holding large amounts of capital—so-called “whales”—who wield disproportionate influence over price and governance.
Addressing Wealth Concentration in Crypto
The concentration of wealth contradicts crypto’s original ethos of decentralization and financial inclusivity. “Whales” can sway markets significantly. However, proponents argue that their long-term interests align with ecosystem health—crashing the market hurts them too.
Still, many new blockchains follow a “pump-and-dump” model. The most successful ones—like Bitcoin and Ethereum—remain relatively decentralized in distribution.

Cryptocurrency and Web3: Which Came First?
Cryptocurrency came first—but Web3 cannot exist without crypto wallets like MetaMask or Coinbase Wallet. These wallets let users carry their assets across digital spaces, forming the backbone of Web3 identity and commerce.
In Web2, you only needed a browser. In Web3, you need a wallet—and funds inside it.
How Should Businesses Adapt?
Companies have two main paths:
- Adopt crypto as payment: With stablecoins (cryptocurrencies pegged to fiat like the US dollar) reducing volatility, businesses from retailers to financial institutions are exploring crypto payments. PayPal, Square (now Block), and even Apple are moving in this direction.
- Engage with broader Web3 ecosystems: Should brands open virtual stores? Issue NFTs? Interact in the metaverse? Luxury brands like Chanel and Gucci already are.
Real-World Use Cases Beyond Hype
PayPal simplifies crypto transfers, challenging traditional remittance services like Western Union. Robinhood is experimenting with blockchain-based stock settlement.
In creative industries, NFTs are revolutionizing music and gaming. Artists like DJ 3LAU and The Chainsmokers use NFTs to bypass traditional labels. Gaming giants like Ubisoft are integrating NFTs into gameplay.
Regulatory Landscape: What’s Next?
Regulation is intensifying—not absent. The EU has restricted energy-intensive proof-of-work blockchains like Bitcoin over environmental concerns. China has banned crypto entirely. The U.S. SEC is tightening oversight, especially on unregistered securities.
While regulation adds complexity, it won’t halt innovation. Instead, it may bring legitimacy and long-term stability.
Environmental Impact: Myth vs Reality
Bitcoin mining consumes significant energy due to proof-of-work mechanics. Once doable on laptops, mining now requires industrial-scale server farms.
But impact depends on energy sources: hydro, solar, or wind reduce harm; coal exacerbates it.
Crucially, not all blockchains are energy-intensive. Many use proof-of-stake or other efficient models. Blaming “crypto” broadly for environmental damage oversimplifies a nuanced issue.
Also, traditional finance consumes vast energy—data centers, ATMs, paper processing. Why single out crypto?

What’s Missing for Mass Adoption?
User experience. Web3 today feels like the internet before browsers—functional but inaccessible to most. We need intuitive tools that make wallets, transactions, and dApps easy for everyday users.
Could Crypto Fail?
Like asking in 1993 if the internet would fail—unlikely. Despite crashes and skepticism, blockchain is here to stay. We often overestimate short-term impact but underestimate long-term transformation.
