An altcoin is any cryptocurrency that isn't Bitcoin. The name simply means 'alternative coin.'
This is a huge and varied group. It includes major networks, small experimental projects, and everything in between.
- Definition: any coin other than Bitcoin
- Thousands of altcoins exist across many networks
- Some are large and established, others are tiny and new
- Not a single category, but a broad label
Common Altcoin Categories
Altcoins are usually grouped by what they're built to do, not just by size.
Knowing the category helps you understand what you're actually buying.
- Platform coins: power smart contracts and apps
- Payment coins: focused on fast, cheap transfers
- Stablecoins: designed to hold a steady price
- Utility tokens: tied to a specific app or service
- Meme coins: driven mainly by community and hype
Risk Compared to Bitcoin
Bitcoin has the longest track record and the widest recognition. Most altcoins carry higher risk than that.
Smaller altcoins can move much faster in price, in both directions, than larger, more established coins.
- Bitcoin: longer history, generally lower relative risk
- Large altcoins: more established, still more volatile than Bitcoin
- Small altcoins: higher potential reward, higher potential loss
- Project failure risk is real, especially for newer coins
Why Liquidity Matters
Liquidity means how easily you can buy or sell without moving the price much.
Popular coins usually have deep order books. Small altcoins can have thin ones, which makes trading them costlier.
- High liquidity: easier entry and exit, tighter pricing
- Low liquidity: price can move a lot on a single order
- Thin markets often mean wider spreads
- Check trading volume before buying an unfamiliar coin
Fees Matter More on Smaller Coins
Some exchanges charge different fees depending on the coin. Less popular altcoins sometimes carry higher costs.
Withdrawal fees can also vary a lot by network, especially for coins on less common blockchains.
- Check if trading fees differ by coin on your exchange
- Compare withdrawal fees before moving altcoins off-platform
- Wide spreads can hide extra cost on thin markets
- Fee differences matter more if you trade frequently
A Short Checklist Before Buying an Altcoin
Take a moment before buying any coin you're unfamiliar with.
This short list helps you avoid the most common early mistakes.
- Know which category the coin falls into
- Check trading volume and liquidity first
- Compare the trading fee and withdrawal fee
- Research the project beyond just the price chart
- Only invest an amount you're fully comfortable losing
