Altcoins, coins, and tokens: What’s the difference?

If you’re new to cryptocurrency and find “crypto-speak” a bit dizzying, it’s probably because both the technology and terms are still evolving, and definitions tend to morph over time. Even those who speak crypto may be unwittingly conflating terms because there aren’t many standardized definitions yet.

Take, for instance, the most basic terms identifying cryptocurrency: coins, altcoins, and tokens. Are they synonymous? According to many sources, they’re not. Yet they’re used synonymously in different contexts:

Is your head spinning? That’s OK; even crypto pros don’t always get it right.

Despite the difficulties in trying to tell crypto apples from crypto oranges—or whether there really is a difference—it helps to understand the basic lingo that’s being thrown around, even if the meanings change or remain uncertain.

A semantic rabbit hole it may be. But here’s a guide to help you explore altcoins, coins, and tokens without falling in.

If the entire cryptocurrency universe expanded from a single point, sort of like a big bang, that point of singularity would be Bitcoin, the first cryptocurrency. Every cryptocurrency that’s not the original Bitcoin is considered an “alternative” to it, hence an “alternative coin” or altcoin.

From this vantage point, an altcoin is every cryptocurrency that’s not Bitcoin. But there’s a caveat to this definition: Not everyone agrees with it.

Bitcoin was designed as an alternative to our everyday standard currency. Ethereum introduced another region to the blockchain universe: one that allowed for innovations such as smart contracts and decentralized applications (dapps) to flourish.

This means that some crypto enthusiasts define an altcoin as any cryptocurrency other than Bitcoin and Ethereum. So “altcoin” refers to any crypto that’s not Bitcoin—or Bitcoin and Ethereum. But if you’re talking about any crypto in the context of its own blockchain network, you refer to them as “coins.”

A coin is a cryptocurrency that comes with its own dedicated and standalone blockchain. In other words, a coin is a specific blockchain’s native cryptocurrency.

For example, the Bitcoin network’s native coin is Bitcoin. Ethereum’s coin is called Ether. Ripple Labs’ coin is called XRP. They each have their own standalone blockchain networks.

Some blockchain networks can be used for other cryptocurrencies and other decentralized applications in addition to their own native coin. This is where things can get confusing, because some of them are called “coins” for the sake of convenience. But technically they’re “tokens.”

A token is a cryptocurrency or crypto asset that runs on another cryptocurrency’s blockchain. An example of a cryptocurrency token is USD Coin (USDC), a fiat-backed stablecoin that runs on the Ethereum blockchain. An example of a crypto asset token is a non-fungible token (NFT). Most NFTs run on blockchains built on the Ethereum network.

Distinguishing coins, altcoins, and tokens is a simple matter of definition. But those definitions aren’t universally accepted, and some are subject to change as the crypto universe evolves.

What truly defines a word or changes its definition is its usage. When you read or hear crypto-speak being slung around, pay attention to the context in which terms are used. As with any other emerging technology, crypto will eventually mature to the point where we’ll agree on a common language.
