Altcoin
Any cryptocurrency other than bitcoin.
Also called: alts · alt
In plain language
Altcoins range from large, established networks to tokens with almost no liquidity. The category spans an enormous range of risk.
Most altcoins are highly correlated with bitcoin, and typically with higher beta: they fall further in declines and rise further in rallies.
Liquidity varies drastically and can vanish during stress, producing spreads and slippage that make stop orders unreliable.
Why it matters
Holding several altcoins is usually one concentrated bet rather than a diversified portfolio, because they tend to move together.
Common mistakes
- Treating a basket of altcoins as diversification.
- Applying bitcoin-sized stops to assets that routinely move several times as far.
- Ignoring how thin the order book becomes outside peak hours.
