Recently, scams in the cryptocurrency space have become rampant, leading to losses of 4.6 billion dollars in 2023 and 500 million dollars already lost in early 2024. Common problems include vulnerabilities in DeFi protocols (like flash loan attacks and oracle manipulation), phishing websites, and fake airdrops. To protect yourself, enhance your security awareness, regularly check and revoke unknown authorizations, use cold wallets for most of your assets, and avoid clicking on unknown links or downloading unfamiliar plugins.
