Comparative performance of cryptocurrencies through the Aumann–Serrano economic index of riskiness
摘要
We present evaluations of cryptocurrencies based on the performance index derived from the Aumann–Serrano—henceforth, AS—economic index of riskiness. Bitcoin is rated quite poorly—much riskier—compared to other cryptocurrencies, although it is the most popular and has the largest market capitalization among all the cryptocurrencies. On the other hand, the stock market ETF, SPY, is rated the best—least risky—and much better than cryptocurrencies by the AS performance index, contrasting sharply to the evaluation made by the Sharpe ratio.
