#CryptoSecurity101 Crypto security is critical for protecting assets on centralized (CEXs) and decentralized exchanges (DEXs). CEXs, like Coinbase, use two-factor authentication (2FA), cold storage, and encryption but are vulnerable to hacks, with $3.7 billion stolen in 2022. DEXs, like Uniswap, enhance security via non-custodial wallets, reducing reliance on centralized servers, but users must safeguard private keys. Common threats include phishing, smart contract exploits, and rug pulls. Best practices include using hardware wallets, enabling 2FA, verifying URLs, and auditing smart contracts. Regulatory compliance and insurance on CEXs add layers of protection, while DEXs prioritize user control, demanding greater personal responsibility.
