“…In literature, a respectable number of academic papers have focused on the return and volatility of cryptocurrencies (Aysan et al , 2019; Balcilar et al , 2017; Bariviera, 2017; Bouri et al , 2017; Chaim and Laurini, 2018; Charles and Darné, 2019; Dyhrberg, 2016; Katsiampa, 2017, 2019; Katsiampa et al , 2019; Koutmos, 2018; Silva et al , 2019).

“…A presença de mudanças de regime nos processos de volatilidade dos logretornos das criptomoedas foi comprovada. Esses resultados vão ao encontro dos obtidos por Silva et al (2019) que também demostraram a existência de dois regimes, um com maior e outro menor volatilidade, ambos com forte característica assimétrica. Outros estudos que documentaram mudanças de regime incluem os de Barivieira et al (2017), Balcome e Fraser (2017), Ardia et al (2019), embora nesses casos, apenas no Bitcoin.…”
