In this paper we will present quantifiable linkages between five different cryptocurrencies, those being Bitcoin, Ethereum, Ripple, Dash and Monero. Initially, we conduct a review of the existing related work. As the concept of cryptocurrencies is fairly new, the relevant literature is very restricted. Attempting to bridge a gap in the existing methodologies, we extract our results by using a five-variable conditional asymmetric GARCH-CCC model, and we conclude that a strong influence exists, of the individual past shocks and volatility in all digital currencies that we include in the research. As estimated by the conditional time-varying covariance, we observe that the interlinkages between the cryptocurrencies are very strong and all covariances follow similar patterns resulting in a highly interdependent and volatile system of assets that is not suitable for a diversified portfolio.
