not sure what you are referring to.


If you look at your link, it reports +308% in the last 52 week period, otherwise known as the last 12 months.


If you are referring to the Goldman analysis, it was for a point in time (they published it late April of this year). The interesting part is the Sharpe ratio because it adjusts for risk. Anyway, it's highly unlikely Goldman's made a math error and even more unlikey that you caught it!

In any case, crypto and possibly investing in financial products does not seem like something you are interested in or even have a basic understanding of how it works. Have fun, use google and a calculator.
