Due to recent developments, several countries have legalised cryptocurrencies, and large corporations have begun accepting them as a form of payment. One of the major concerns in this field is market efficiency, specifically regarding whether the cryptocurrency market follows the random walk hypothesis. To investigate this issue, analysed the top ten cryptocurrency prices spanning from March 11, 2020, to March 26, 2023, focusing on the period following the declaration of the global pandemic. The study employed several statistical validity tests, including the Ljung-Box test, runs test, Bartels’s test, variance ratio test, EGARCH (1,1) and R/S Hurst exponent. The study revealed that most cryptocurrencies do not conform to the random walk hypothesis, indicating that the market is inefficient. This study implies that investors may be able to earn abnormal profits through the use of arbitrage strategies in this young market.
