In the fast-evolving world of Web3, cryptocurrency symbols have become part of our daily digital language. Whether you're tracking prices on an exchange, browsing NFTs on a marketplace, or scrolling through crypto updates on social media, these minimalist logos appear everywhere—silent yet powerful representations of decentralized value.
But have you ever paused to wonder where these symbols come from? Who designed them? What do they mean? Behind each icon lies a story shaped by community input, design evolution, and cultural context. Let’s explore the origins and meanings behind four major cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), BNB, and Solana (SOL)—and how their visual identities reflect broader shifts in digital finance.
The Origins of Currency Symbols: From $ to Blockchain Logos
Before diving into crypto-specific emblems, it's worth understanding the legacy of traditional currency symbols—especially the ubiquitous dollar sign ($).
Historically, the "$" symbol likely evolved from the Spanish *peso*, with early handwritten notations combining the letters "p" and "s" into a stylized "pˢ". Over time, the "s" overtook the "p", forming the familiar $ shape by the late 18th century.
Another compelling theory ties the double-barred version to the Pillars of Hercules on the Spanish coat of arms—symbolizing strength and global reach. These pillars were often depicted with a ribbon wrapped around them in an "S"-like form, later influencing coinage and eventually the dollar sign.
This blend of historical symbolism and functional evolution sets the stage for how modern cryptocurrency logos are conceived—not just as brand marks, but as cultural artifacts.
Bitcoin (BTC): A Logo Shaped by Community Rejection
The first Bitcoin logo appeared in early 2009 on Satoshi Nakamoto’s original client software. It featured a literal gold coin stamped with “BC”—a nod to metallism, the idea that money derives value from physical commodities like gold.
But this metallic motif didn’t last long.
In February 2010, Nakamoto introduced a revised design: a stylized capital B with two vertical lines cutting through it—inspired by the dollar sign, but distinct in that the lines ran from top to bottom without crossing the center. While functional, many users found it underwhelming.

Nakamoto himself admitted he wasn’t confident in his design skills and invited others to improve upon it—an early example of open-source collaboration in action.
Enter bitboy, an anonymous forum user who in November 2010 posted a now-iconic redesign: an orange circle with a tilted "₿" symbol rotated 14 degrees clockwise. The vibrant color and sleek typography stood out immediately.
Interestingly, bitboy revealed that Mastercard’s logo inspired his design—a pointed irony given Bitcoin’s mission to disrupt centralized financial systems. Yet the similarities are undeniable: bold sans-serif font, dynamic tilt, and vivid orange tones.
Despite its accidental resemblance to corporate branding, bitboy’s version won widespread approval. He released it under open license, cementing Bitcoin’s identity as a community-driven project—not one dictated by a single authority.
Ethereum (ETH): From Sigma to Symbolism
Unlike Bitcoin’s grassroots evolution, Ethereum’s logo was born from necessity just before its 2015 launch. One of Ethereum’s co-founders sketched an initial concept using basic software: two rotated ∑ (sigma) symbols combined at 45-degree angles, creating a diamond-like shape.
While mathematically elegant, this prototype lacked depth. So the team launched a community design contest and selected a refined version: a three-dimensional octahedron made of six triangles—four above, two below—with varying opacity levels (45%, 60%, 80%) to create a striking立体 effect.
Today, this eight-faced geometric form is instantly recognizable across wallets, dApps, and NFT platforms. Its clean symmetry has inspired countless interpretations: some see it as a crystalline structure, others as a metaphor for decentralized networks or mathematical perfection.
Yet according to George Hallam, a core Ethereum contributor, there’s no hidden meaning: “It’s just an octahedron.”
Still, the logo’s adaptability speaks volumes. Variants include solid black silhouettes, hollow gradient versions, pink for WETH (Wrapped ETH), and customized forms for projects like ENS (Ethereum Name Service)—proving that even minimal icons can evolve with ecosystem growth.
Solana (SOL): Futurism in Purple and Green
Later entrants like Solana took a more centralized branding approach. Designed with clear corporate guidelines, the Solana logo features three parallel parallelograms—evoking speed, motion, and architectural precision.
Inspired by 1980s tech aesthetics, the design uses a distinctive purple-to-green gradient, reinforcing its identity as a high-performance blockchain built for scalability and innovation.

The brand enforces strict usage rules: standard colors, spacing ("clear space"), proportions, and application examples—all hallmarks of professional brand management. This consistency extends into its ecosystem, where DeFi apps, NFT marketplaces, and gaming platforms frequently adopt Solana’s signature hues.
This deliberate color strategy creates instant visual cohesion across dApps—making Solana one of the most recognizable ecosystems in Web3.
BNB: The Power of Simplicity and Color
Binance’s logo—a yellow interlocking cube structure—mirrors its platform’s emphasis on connectivity and modular architecture. Viewed from above, the negative space forms linked blocks, symbolizing blockchain technology itself.
Initially launched with nearly identical visuals, the logo underwent a subtle refinement after one year: reducing the gap between rectangular segments from a 1:1 ratio to 7:5 width-to-spacing, enhancing visual density and focus.
Available in multiple perspectives—top-down, orthographic, 3D—the BNB symbol maintains strong contrast against dark backgrounds commonly used in trading interfaces. The bright yellow hue ensures visibility while avoiding confusion with red/green price indicators.
This strategic use of color not only strengthens brand recall but also differentiates Binance from competitors—a crucial edge in a crowded exchange landscape.
Should Decentralized Currencies Have Official Logos?
Bitcoin emerged through community consensus; Ethereum evolved via collaborative refinement; Solana and BNB reflect top-down branding. This contrast raises a critical question:
Should decentralized currencies have official logos at all?
On one hand, standardized symbols reduce confusion and enhance usability—especially important as crypto enters mainstream adoption. On the other, rigid branding contradicts decentralization principles. After all, shouldn't identity emerge organically?
Historically, symbols like arrows or hearts gained meaning through common use—not decree. Could crypto logos follow suit?
Cultural Identity in Digital Form
Beyond utility, these symbols carry cultural weight. Just as people once mocked corporate greed by writing “Micro$oft” or “Di$ney,” Ethereum enthusiasts now replace “E” with “Ξ” (the Greek Xi)—a subtle act of allegiance to decentralized ideals.
Is this resistance to traditional capitalism—or simply a shift in what we worship? As meme coins featuring dogs, sushi, and unicorns gain traction, money itself becomes performance art.
