**What about “hijacking Bitcoin”?**
- The Bitcoin protocol itself has not been “hijacked.” The biggest losses in crypto come from exchange/wallet breaches and bridge/smart-contract exploits—not from breaking Bitcoin’s core consensus.
- A 51% (majority hash-rate) attack on Bitcoin would be extraordinarily expensive and difficult. Even then, it cannot steal others’ coins or change the 21M supply; it could at most censor transactions or attempt short-term double-spends of the attacker’s own funds.
- More realistic risks for users are off-chain and endpoint issues: exchange hacks, wallet malware, phishing/SIM swaps, and occasional network-level tricks (e.g., node eclipse/BGP routing attacks). These don’t “hijack Bitcoin,” but can compromise users or infrastructure around it.
