This letter has investigated the exogenous shocks (climate change and the Russia-Ukraine war) in the top ten digital currencies' price dynamics. Therefore, we use the information theory quantifiers. We discover that the exogenous shocks have an ambiguous effect on the informational efficiency of these digital currencies. Our results shed light on the potential of altcoins to support exogenous shocks and their capability to use with portfolio selection, risk diversification and herding behaviour.
