ATH

Bitcoin set a new ATH of nearly $69,000 in November 2021 before the prolonged bear market began.比特币在 2021 年 11 月创下了近 69,000 美元的历史最高价（ATH），随后漫长的熊市便开始了。

Many altcoins have never reclaimed their previous ATH, a reminder that speculative peaks are rarely sustained.许多山寨币再也没有收复它们先前的历史最高价，这提醒人们投机性高点很难维持。
