What Is an Altcoin Breakout?
In crypto trading, a breakout occurs when an asset’s price moves decisively above a resistance level—or below support—with increased trading volume, often signaling the start of a new trend. On breakout, resistance levels can become new support, and vice versa . Traders look for confirmation such as strong volume or retests to confirm breakout validity and avoid fakeouts .
When applied to altcoins, a breakout typically refers to:
Individual altcoin breakouts, like Solana surging past technical thresholds.
Altcoin market-wide breakouts, such as the total altcoin market cap or Bitcoin dominance shifting to favor altcoins—often visualized through repeated support/resistance flips .
