彩虹图(Rainbow Chart)是一种用来分析比特币价格走势的图表工具,常被加密货币投资者用来判断市场趋势和价格周期。它不是基于复杂算法,而是用颜色带直观展示比特币价格的长期变化,帮助投资者判断当前市场是“低估”还是“高估”。 简单来说,彩虹图把比特币的历史价格按对数刻度(log scale)绘制,用不同颜色带表示价格区间: - **蓝色/绿色**:通常表示价格较低,可能是买入的好时机(市场“低估”)。 - **黄色/橙色**:表示价格适中,市场处于正常波动。 - **红色**:表示价格过高,可能接近泡沫顶端(市场“过热”)。 这些颜色带是基于历史价格数据和对数回归模型粗略拟合的,反映了比特币价格随时间增长的趋势。它的核心逻辑是:比特币价格长期看涨,但在不同周期会有回调和调整,彩虹图通过颜色直观提示这些周期。 使用时要注意: 1. **不是预测工具**:彩虹图只反映历史趋势,不能精准预测未来。 2. **结合其他指标**:单独看彩虹图可能误导,最好搭配其他技术分析或基本面分析。 3. **适合长线**:它更适合长期投资者,而非短线交易者。 总之,彩虹图就像一个简化的“市场情绪指南”,用颜色帮你快速判断比特币价格的大致位置,但别完全依赖它做决策。
