Análise exploratória sobre a tecnologia blockchain: uma comparação do comportamento de criptomoedas e moedas tradicionais para o período da Covid-19

Abstract

Considering the increasing popularity of cryptocurrencies and the relevance of blockchain as the technological foundation for such digital assets, the present study aims to analyze blockchain technology by comparing the volatility of cryptocurrencies, bitcoin, and ethereum, with that of traditional internationally circulated currencies, the US Dollar and the Euro, during the peak period of the Covid-19 pandemic. The purpose is to verify if currencies traded via blockchain technology exhibit greater stability, given a moment of heightened uncertainty. In order to address the stated objective, a descriptive analysis of the price series of the aforementioned currencies was conducted, along with the decomposition of these series and tests of stationarity. As the main result, it was found that, for the analyzed period, cryptocurrencies exhibited volatility levels as high as those of traditional currencies.
