Interaction effect of ${\text{Cases}}_{[-7,-1]}\times {\text{Policy}}_t$ (left-panels) and ${\text{Deaths}}_{[-7,-1]}\times {\text{Policy}}_t$ (right-panels) for Ethereum (top), Bitcoin (middle), and CCi30 (bottom). The upper, middle and lower lines on each graph depict increasing, constant, and decreasing global policy stringency (${\text{Policy}}_t$) respectively.
