Cognitive biases are mental shortcuts that usually involve focusing on one aspect of a complex problem and ignoring others, often resulting in faulty or illogical reasoning. In web3 and crypto contexts, these biases can influence investors, developers, and users, affecting decision-making processes, risk assessment, and overall engagement with decentralized technologies. Common types of cognitive biases include confirmation bias, anchoring bias, and overconfidence bias, which can have significant implications in the fast-paced environment of cryptocurrency trading and investment.
