20% of $126,180 = $25,236. From MapleAI: “According to historical price data, Bitcoin has fallen by 80% or more from a new all-time high price in dollars on two occasions: 1. 2011: Bitcoin reached an all-time high of $31.91 on June 8, 2011, and then fell to $2.22 on November 18, 2011, a decline of approximately 93%. 2. 2017:: Bitcoin reached an all-time high of $19,666 on December 17, 2017, and then fell to $3,217 on December 15, 2018, a decline of approximately 83.6%. Note that these declines are based on nominal prices and do not account for inflation or other economic factors. Additionally, it's worth noting that Bitcoin's price has been highly volatile throughout its history, and significant price swings are not uncommon. It's also worth mentioning that there have been other significant declines in Bitcoin's price, such as the 2013-2015 bear market, where the price fell by around 85% from its peak. However, the two instances mentioned above are the most relevant to the question, as they represent declines from new all-time high prices.” #HODL
