Big Data Analysis of Cryptocurrency Exchange Rate Changes Dynamics

Abstract

The article analyzes the dynamics of changes in the exchange rate of cryptocurrencies such as DogeCoin, Bitcoin, BinanceCoin and AaveCoin in recent years (before COVID-19, during the pandemic and the war in Ukraine). At the same time, in the first quarter of 2020, the spread of the COVID-19 pandemic and the related active campaign of the National Bank and banks to support online operations and services was an additional factor contributing to the population’s rejection of cash. The war, among other things, encouraged more people in Ukraine to believe in cryptocurrency.
