The results of the research according to the GARCH model indicate that in general there is a negative correlation between the percentage of changes in the coin bubble and the changes in the total index, and this negative correlation can be proven according to the effect of heterogeneous variance according to the estimation model between the variable of bubble fluctuations and the price of the capital and coin market.
