The results of This study, that The CSGARCH (1.1) model is the optimized model for estimating the returns of Ethereum, and the GARCH (1.1) model is the optimized model for estimating the returns volatility of Ethereum Classic, It also turns that recent information has a greater impact on volatility.Arالاثيريوم ; العملات المشفرة ; سلسلة الكتل ; نموذج CSGARCH ; جائحة كوروناArticle
