Cryptocurrency commentator PlanB: Bitcoin is the only asset with a Sharpe ratio greater than 1

According to Bitcoinist, cryptocurrency commentator PlanB tweeted that Bitcoin is the only asset with a Sharpe ratio greater than 1. PlanB believes that Bitcoin's return is much higher than other more popular assets, such as FAANG stocks that have dominated the past decade. Considering that his calculation model did not take into account the historical price of Bitcoin in the first few years, this result is surprising. In 2012, the value of this emerging cryptocurrency rose from $ 0.83 to a high of $ 424. PlanB did not release bitcoin price data for 2009-2012. Former options trader and risk analyst and author of "Black Swan Effect" Nassim Nicholas Taleb said that the Sharpe ratio is not applicable to Bitcoin. Note: The Sharpe ratio indicates the return growth rate caused by additional fluctuations in assets when an investor holds a higher risk asset.
