  This research mainly explores the characteristics of different strategies and
whether VIX INDEX positively influences the investment portfolio in any period.
Our portfolio has six significant cryptocurrencies, VIX INDEX and gold. We
perform parameter estimation on all raw data and bring the two types into
different investment strategies, complete them effectively according to other
characteristics, and compare the results. At the same time, we make two
different portfolios, one contains VIX INDEX, and one does not have VIX INDEX.
We use different portfolios in different portfolio strategies and find that VIX
INDEX can positively impact the investment portfolio of cryptocurrencies, no
matter in the standard market or the downward market. The research shows that
gold has the same attributes as VIX INDEX and should have a specific positive
effect, but no comparative experiment has been done.
