$SUI An altcoin breakout refers to a sudden significant increase in the price of a cryptocurrency alternative to Bitcoin, surpassing an important technical resistance. This movement often signals a change in trend and attracts the attention of traders. It is usually preceded by consolidation or a chart pattern (triangle, flag, etc.). The volume increases, indicating growing interest from investors. A confirmed breakout can lead to a short-term price acceleration. However, false breakouts are common, hence the importance of waiting for confirmation (closing above resistance). Altcoins often react to Bitcoin movements and the overall sentiment of the crypto market.
