Cryptocurrencies, or plainly stated hereof as “Cryptos”, have always been at the center of attention for
numerous institutional and individual investors, since their inceptions and categorization as digital currencies.
Nowadays, cryptocurrencies market is mostly like a global hotspot. Albeit, they have recently been regulated
by numerous financial institutions worldwide. The global regulatory framework imposed by banks, classified
them as unique digital currencies or digital currency schemes. Moreover, their lucrative returns are extremely
high and volatile compared to the ones of major global stock indices and gold. Our sample comprises of three
of the oldest cryptocurrencies: Bitcoin, XRP and Litecoin, totaling a 70% market share. We include
observations from the period from October 1, 2013 till October 1, 2020 and we treat them as our dependent
variables. Our explanatory variables are of the same period of examination and consist of six global stock
indices, being: S&P 500 (United States of America, U.S.A.), FTSE 100 (United Kingdom, U.K.), S&P/ASX
200 (Australia), STOXX50E (Europe), Nikkei 225 (Japan), HSI (Hang Sheng Index, Hong Kong) and the
commodity of gold. By applying a General AutoRegressive Conditional Heteroskedasticity (“GARCH”), we
analyze the total risk and the relationship between the returns’ volatility of the three cryptocurrencies and the
influence of returns of the six stock indices and gold upon them. Our results are adequately backed by prior
research that indicates cryptocurrencies, in their vast majority, are not strongly interrelated with the stock
markets and gold, even after the force-majeure strike of the newly pandemic COVID-19. Therefore, they are
located somewhere in between, creating a new, unique asset class, a new investment opportunity.
