Abstract: This study provides a formal analysis on the structural breaks and volatility spillovers in seven largest cryptocurrencies including Bitcoin, Litecoin, Ripple, Stellar, Monero, Dash, and Bytecoin. Cumulative sum test for parameter stability, Granger Causality test, LM test for ARCH and Dynamic conditional correlation MGARCH model indicate that: (1) the structural breaks are universally present in these popular cryptocurrencies; and (2) the shifts spread from smaller cryptocurrencies (in market capitalization) to larger ones. Notably, volatility spillovers also exist with strong positive correlations among cryptocurrencies. Our findings highlight the limit of diversification benefits within the cryptocurrency market itself.
