In crypto, 'coin' and 'token' are often used interchangeably, but they're technically different. A coin is the native currency of its own blockchain — Bitcoin (BTC) on the Bitcoin network, ETH on Ethereum, SOL on Solana. A token is a digital asset created on top of an existing blockchain using a standard like ERC-20 — USDC, UNI, LINK, and thousands of others are tokens built on Ethereum. The distinction matters for understanding how assets work and what gives them value.
Token standards define the rules that tokens must follow on a blockchain. ERC-20 is the most common — it specifies functions like transfer, approve, and balanceOf that every ERC-20 token implements, ensuring they all work seamlessly with wallets, exchanges, and DeFi protocols. ERC-721 is the standard for NFTs (unique tokens). ERC-1155 supports both fungible and non-fungible tokens in one contract. Solana uses SPL tokens, and BNB Chain uses BEP-20 — similar concepts adapted for different blockchains.
Utility tokens (UNI, AAVE) grant access to a protocol's features or governance. Governance tokens give voting rights over protocol decisions. Security tokens represent ownership in real-world assets and are regulated like traditional securities. Stablecoins (USDC, USDT) maintain a stable value pegged to fiat. Meme tokens (PEPE, DOGE) derive value primarily from community and speculation. Wrapped tokens (WBTC, WETH) represent assets from other chains. Understanding what type of token you're buying helps assess its value proposition and risk profile.
Token standards define common interfaces that wallets and exchanges can interact with. ERC-20 is the most universal — fungible tokens like USDC, LINK, and UNI all implement this standard. ERC-721 powers NFTs where each token is unique. ERC-1155 (used by gaming projects) supports both fungible and non-fungible tokens in a single contract for efficiency. ERC-4626 standardizes yield-bearing vault tokens. Solana's SPL tokens serve a similar role to ERC-20 but with Solana-specific design (token accounts, mint authority). Standardization accelerates ecosystem development — once a wallet supports ERC-20, it works with thousands of tokens out of the box, dramatically lowering integration costs.
Fungible tokens are interchangeable — one USDC is identical to any other USDC. Most cryptocurrencies are fungible. Non-fungible tokens have unique properties — your CryptoPunk #7804 is fundamentally different from #7805, even though both are part of the same collection. Semi-fungible tokens (ERC-1155) support both modes; for example, an in-game item type might be fungible (you have 5 health potions, all interchangeable) while a unique sword is non-fungible. The fungibility distinction matters for everything from regulatory treatment to user experience to technical implementation.
Token value comes from a combination of utility, scarcity, demand, and narrative. Utility tokens derive value from usage — paying gas, accessing services, or earning yield. Governance tokens give holders voting rights over protocol decisions. Security tokens represent ownership of off-chain assets like equity or real estate. Memecoins derive value almost purely from cultural resonance and community. Most successful tokens combine multiple value drivers: ETH provides utility (gas), yield (staking), and store-of-value properties. The biggest mistake new investors make is assuming all tokens have similar value mechanisms — understanding what drives a specific token's demand is essential before investing.
A coin has its own native blockchain (BTC on Bitcoin, ETH on Ethereum, SOL on Solana). A token is built on top of an existing blockchain (USDC, UNI, LINK on Ethereum; BONK on Solana). The terminology is loose — 'crypto' covers both — but the technical distinction affects how the asset is created, transferred, and secured.
Yes. Creating an ERC-20 token on Ethereum or an SPL token on Solana takes minutes and costs less than $50 in gas. Pump.fun on Solana has automated this further — anyone can launch a token with a few clicks. The hard part isn't creating tokens; it's giving them sustainable value, building community, and earning genuine demand.
It depends on the token and jurisdiction. The SEC applies the Howey Test — tokens with profit expectations from others' efforts are typically deemed securities. Bitcoin and (increasingly) Ethereum are generally not considered securities in the US. Many other tokens exist in regulatory gray zones. Outside the US, jurisdictions like Singapore, Switzerland, and the UAE have created clearer crypto-specific frameworks. Utility tokens that provide access to a service may receive different treatment than tokens designed primarily as investments, though the distinction is often blurry. The regulatory landscape continues to evolve rapidly, with new legislation in the EU (MiCA), UK, and Asia providing more structured classifications. Consult local regulations before issuing or trading tokens at scale, and be aware that tokens may be classified differently in different countries.
Wrapped tokens represent assets from one blockchain on another — for example, WBTC is Bitcoin wrapped for use on Ethereum. The original asset is locked by a custodian or smart contract while the wrapped version circulates on the destination chain. This enables cross-chain liquidity without native interoperability.
