The cryptocurrency industry has evolved from a niche technological experiment into a global financial phenomenon. Yet, despite its rapid growth, many investors still struggle to understand the core of what they're investing in—especially when it comes to public blockchains. What exactly are we buying when we invest in a blockchain network? And more importantly, what makes some blockchains thrive while others fade into obscurity?
At the heart of this question lies a simple but powerful financial principle: P = E × PE, or Price equals Earnings multiplied by Price-to-Earnings ratio. This formula, long used in traditional finance, applies equally to blockchain assets. In the long run, an asset's value is determined not by hype or speculation alone, but by real earnings and market perception of future potential.

Understanding the Two Pillars: Earnings and Valuation
The Role of Valuation (PE)
Valuation—represented by the PE ratio—is influenced by numerous factors: growth potential, interest rates, market penetration, total addressable market size, monetary policy, and competitive dynamics. Legendary investor Warren Buffett famously avoids Bitcoin because it doesn’t produce cash flow. While he’s correct that BTC lacks intrinsic earnings today, his view focuses only on the earnings side (E), overlooking the valuation component (PE).
In reality, assets like meme coins or even Bitcoin can be seen as vehicles driven purely by valuation—by narrative, adoption momentum, and network effects. As long as new participants keep entering, prices can rise without traditional cash flows. But there’s a critical caveat: the larger the market cap becomes, the harder it is to sustain growth without real revenue. At some point, belief must be backed by utility.
The Foundation of Value: Earnings (E)
Earnings come from revenue—and revenue comes from a clear business model. A business model defines how an entity generates income by providing value through goods or services. In traditional markets, companies like Amazon or Apple earn via product sales, subscriptions, or advertising.
So what’s the crypto equivalent?
The Emerging Business Models in Blockchain
The crypto ecosystem has developed several distinct revenue-generating mechanisms:
- Blockspace fees (GAS fees)
- Swap fees (DEXs/CEXs)
- Lending interest spreads
- Stablecoin seigniorage and transaction fees
- MEV (Maximal Extractable Value)
Among these, blockspace monetization stands out as a revolutionary innovation unique to blockchain.
Blockspace: The New Digital Real Estate
Blockchain introduced a radical shift: users pay directly for computational resources. Every transaction—whether sending tokens, interacting with smart contracts, or minting NFTs—requires payment in GAS fees. These fees are not arbitrary; they represent real economic value for access to decentralized computation, storage, and bandwidth.
Contrast this with the traditional internet. For decades, companies like Google or Facebook bore the infrastructure costs (e.g., AWS bills) and monetized users indirectly through ads or data. The web was—and largely remains—free at the point of use.
Blockchain flips this model: the user pays upfront. This transforms blockchains into self-sustaining economic systems where demand for usage directly fuels revenue.
In 2023 alone, users paid billions of dollars in GAS fees across major networks. If a blockchain generates $1 billion in annual revenue and trades at a 20x PE ratio, its valuation could reach $20 billion—entirely justified by fundamentals.
Take TRON as an example. With over $60 billion worth of USDT issued on its chain—nearly half the global supply—it generated approximately $400 million in fee revenue in 2023, mostly from USDT transfers. Applying even conservative multiples, this supports a substantial valuation.
But here's the real question: Can this scale tenfold—or even a hundredfold—in the next decade?
Why Public Blockchains Dominate Market Caps
Many wonder why Layer 1 blockchains occupy so many spots in the top 100 cryptocurrencies by market cap. The answer lies in their clear path to revenue generation.
Unlike speculative projects with vague promises, top-tier blockchains have built-in economic engines:
- Ethereum earns from every dApp interaction.
- Solana captures fees from high-frequency trading and DeFi activity.
- Bitcoin, though limited in functionality, secures value transfer and earns mining fees.
These networks aren’t just protocols—they’re platforms with recurring revenue models, akin to cloud providers charging for compute time.
Compare that to countless altcoins with no revenue mechanism, no product-market fit, and no path to profitability. They rely solely on price appreciation fueled by marketing narratives—a dangerous game in the long run.
Technology vs. Business Model: A Critical Distinction
Too often, crypto projects emphasize technical jargon—ZK-proofs, modular architecture, parallel EVMs, L2 rollups—without answering the fundamental question:
How does this generate revenue?
While technological advancement is essential, it must serve a commercial purpose. Ask any founder: innovation without monetization leads to bankruptcy.
We’ve seen this before. The dot-com bubble burst because many companies had flashy websites but no way to make money. Today’s crypto space risks repeating history if teams prioritize engineering elegance over economic sustainability.
So before getting dazzled by "revolutionary tech," ask:
- Does this increase user demand for blockspace?
- Can it capture more transaction volume?
- Will it reduce costs while improving margins?
Only then does the technology create shareholder value.

Frequently Asked Questions (FAQ)
Q: Can a blockchain have value without generating revenue?
A: In the short term, yes—through speculation or network effects. But long-term value requires sustainable earnings. Without revenue, a blockchain relies entirely on ever-increasing adoption, which is difficult to maintain at scale.
Q: Are GAS fees just a tax on users?
A: Not exactly. GAS fees are market-driven payments for scarce computational resources. They prevent spam and ensure network security. In well-designed systems, higher usage leads to higher fees—and thus higher protocol revenue.
Q: How do I evaluate which blockchain has the best business model?
A: Look at metrics like fee revenue over time, active addresses, developer activity, and real-world usage. Compare them against market cap to assess valuation efficiency. Networks with growing usage and rising fees are typically stronger investments.
Q: Is staking yield a form of profit?
A: Staking rewards are often inflationary rather than profit-based. True profit comes from fees burned or distributed to stakeholders—not newly minted tokens diluting supply.
Q: Will Layer 2 solutions undermine Layer 1 revenue?
A: Only if they fully decouple economically. Many L2s still settle back to L1s and pay fees there. The ideal scenario is a symbiotic ecosystem where L1 secures base-layer trust and L2s scale usage—both capturing value.
Q: What’s the future of blockchain profitability?
A: As blockchain use expands beyond speculation into real applications—payments, identity, gaming, supply chain—the demand for secure, transparent computation will grow. Blockchains that efficiently monetize this demand will dominate.
Final Thoughts: Invest in Substance, Not Hype
The crypto market will likely see tens of thousands of projects emerge over the next decade. Most will fail—not due to poor technology, but because they lack a viable business model.
True investing means identifying the rare few that combine strong fundamentals with scalable revenue. It means looking past buzzwords and asking hard questions about sustainability.
As the industry matures, the winners won’t be those with the loudest marketing—but those with the clearest path to profit.
Don’t wait for perfection. Start evaluating projects like a venture capitalist: focus on unit economics, market fit, and long-term viability.
Because in the end, time favors those who build—and invest—wisely.
