What Is ‘Information Asymmetry’ and How Does It Relate to Market Efficiency in Crypto?
Information asymmetry is a situation where one party in a transaction has more or better information than the other. In crypto, this can be due to insider knowledge, faster news feeds, or privileged on-chain data access.
This asymmetry directly violates the Strong and Semi-Strong forms of EMH. Arbitrageurs who possess an information advantage can profit from mispricing before the information is fully reflected in the price, reducing efficiency.
