Why is this important?
1. Asset protection – Cryptocurrencies are stored in wallets, and if an attacker gains access to the private keys, the funds can be lost forever.
2. Decentralization = user responsibility – Unlike banks, there is no centralized protection in crypto, so security depends on you.
3. Fraud and hacking attacks – Phishing, malware, exchange hacks (e.g., Mt. Gox, FTX) show how vulnerable systems can be.
4. Privacy – The blockchain is transparent, but protection methods (e.g., CoinJoin, private wallets) help maintain anonymity.
