In the fast-evolving world of Web3, cryptocurrency symbols have become more than just digital representations of value—they’re cultural icons. From Bitcoin’s bold ₿ to Ethereum’s geometric diamond, these logos carry stories of innovation, community collaboration, and design evolution. But where did they come from? Who designed them? And what do they really mean?
Let’s explore the fascinating origins and hidden narratives behind some of the most recognized cryptocurrency symbols today.
The Origins of the Dollar Sign: A Historical Prelude
Before diving into digital currencies, it's worth understanding the legacy of traditional monetary symbols—especially the ubiquitous "$". While its exact origin is debated, the most widely accepted theory traces it back to the Spanish peso, used in the Americas during the 18th century.
Early handwritten records show a stylized "pˢ" (an abbreviation for peso), where the "s" gradually overlapped the "p", eventually simplifying into the "$" we recognize today. Another compelling theory links the double-barred version of the symbol to the Pillars of Hercules—a motif on Spanish coins depicting two columns wrapped in a ribbon, symbolizing strength and exploration.
These historical roots highlight how currency symbols evolve not through official decrees, but through cultural adoption and visual shorthand—principles that still apply in the decentralized world of crypto.

Bitcoin: A Symbol Shaped by Community
Bitcoin’s journey began in 2009 when Satoshi Nakamoto introduced a simple coin-like logo with “BC” inscribed—reflecting metallist ideals, where value stems from tangible assets like gold. This early design emphasized Bitcoin as digital gold.
By February 2010, Nakamoto proposed an updated version: a bold "B" with two vertical lines, inspired by the dollar sign. However, unlike "$", the lines didn’t cross through the letter, preserving a distinct identity. Despite being functional, many users felt it lacked long-term appeal.
Enter “bitboy,” an anonymous forum user who in November 2010 shared a redesigned logo featuring a vibrant orange circle and a tilted ₿ character rotated 14 degrees clockwise. This version quickly gained popularity for its modern, dynamic look.
Interestingly, bitboy admitted his inspiration came from Mastercard and Visa—ironic, given Bitcoin’s mission to disrupt centralized financial systems. Yet this contrast underscores a deeper narrative: crypto isn’t just about technology; it’s about challenging established norms.
The ₿ symbol has since been standardized in Unicode (U+20BF), cementing its place in digital communication.
Ethereum: Simplicity Meets Misinterpretation
The original Ethereum logo was hastily created just before launch by one of its co-founders using basic graphic software. It featured two rotated ∑ (sigma) symbols forming a diamond-like shape—a nod to mathematical precision and computational power.
Later, a community design contest refined this concept into the now-familiar eight-sided geometric diamond, composed of six triangles (two at the bottom, four at the top). Using varying opacities (45%, 60%, 80%), the design achieves a striking 3D effect.
Despite widespread speculation—some interpret it as a diamond crystal or sacred geometry—the truth is more pragmatic. As Ethereum contributor George Hallam clarified: “There’s no hidden meaning. It’s simply an octahedron.”
Yet, the symbol’s adaptability shines across use cases: solid black for branding, transparent gradients for apps, pink variants for WETH, and customized versions for ENS domains.
This flexibility reflects Ethereum’s ethos: open, modular, and endlessly extensible.
Solana: Futurism in Purple and Green
Unlike Bitcoin or Ethereum, Solana’s branding emerged from a centralized design team aiming for strong visual identity. Inspired by 1980s tech aesthetics, the logo features three parallelograms suggesting speed, structure, and innovation.
The signature purple-and-green color scheme creates high contrast and instant recognition. This palette has permeated Solana’s ecosystem—DeFi platforms, NFT marketplaces, and gaming dApps often adopt similar hues to signal affiliation.
Solana even publishes official brand guidelines covering spacing, proportions, and usage rules—akin to traditional corporate identity systems. This level of control ensures consistency but contrasts with the organic growth seen in earlier cryptocurrencies.

BNB: Blocks in Yellow
Binance’s logo embodies blockchain’s core concept—interconnected blocks. Viewed from above, the yellow interlocking cubes suggest data flow and network connectivity.
Initially launched with near-final design, Binance later refined the spacing between elements (adjusted from 1:1 to 7:5 width-to-gap ratio) for better visual cohesion. Multiple versions exist: top-down flat views, isometric renders, and 3D cubes—ensuring versatility across platforms.
The bold yellow stands out against dark backgrounds commonly used in trading interfaces, avoiding confusion with red/green price indicators. This strategic choice reinforces BNB’s role as both a utility token and a brand anchor within one of the world’s largest exchanges.
Should Cryptocurrencies Have Official Logos?
This brings us to a philosophical question: In a decentralized ecosystem, should any entity have authority over a symbol?
On one hand, standardized logos reduce confusion—critical as adoption grows. On the other, grassroots evolution aligns with crypto’s anti-establishment roots. Bitcoin’s community-driven process contrasts sharply with Solana’s top-down approach.
Perhaps the answer lies in balance: core symbols can stabilize recognition, while allowing room for creative reinterpretation—much like emojis or internet memes.
Cultural Shifts in Symbolism
Currency symbols also reflect cultural attitudes. Historically, "$" was mocked in phrases like "Micro$oft" to critique capitalism. Now, Ethereum enthusiasts replace "E" with "Ξ" (Greek Xi) in usernames or hashtags—a badge of loyalty to decentralization.
Is this irony? Or simply a new form of tribalism? Either way, it shows how symbols transcend finance—they become identities.
The Evolution of Value Representation
From gold-backed coins to abstract glyphs, our representation of value has transformed dramatically. Today, animals (Dogecoin), food (SushiSwap), and even fictional creatures (Unicorn Token) serve as monetary symbols.
This shift reflects broader changes in how society perceives value—not just in utility or scarcity, but in community, narrative, and shared belief.
Frequently Asked Questions
Q: What does the Bitcoin symbol ₿ represent?
A: The ₿ symbol combines a "B" with two vertical lines, symbolizing Bitcoin’s identity as a digital currency distinct from traditional fiat systems like the US dollar ($).
Q: Why does Ethereum’s logo look like a diamond?
A: It represents an octahedron—a geometric shape made of eight triangular faces. While often interpreted symbolically, its creators confirm it was chosen primarily for aesthetic and structural clarity.
Q: Who designed the Solana logo?
A: Developed by Solana’s internal team, the logo follows professional branding standards with defined colors, spacing, and usage rules to maintain consistency across its growing ecosystem.
Q: Is there an official BNB logo guideline?
A: Yes. Binance provides detailed brand assets including color codes, spacing requirements, and logo variations to ensure uniformity across platforms and marketing materials.
Q: Can anyone create a new cryptocurrency symbol?
A: Absolutely. In decentralized networks, symbols often emerge organically from community use. However, widespread adoption depends on recognition and consensus.
Q: Why do some Ethereum users write “Ξ” instead of “E”?
A: It's a stylistic nod to Ethereum’s symbol (Ξ), used online to express affiliation or enthusiasm for the network—similar to fan culture in other tech communities.
