Bitcoin, Ethereum, and most of the projects out there have never had their protocol compromised. There are a few exceptions -- the biggest ones being Ethereum Classic (ETC) and MIOTA. ETC had their protocol compromised by a 51% attack, MIOTA's system is most likely not even a real blockchain, after being audited by the MIT Technology Review. But we call them "zombie chains" because the blockchain allows for these projects to persist, even though it's dead.
You obviously do not know what you speak about because the network has never been hacked . The wallet was hacked due to a third party add-on

@Ngaudi Ethereum Classic is literally Ethereum. Ethereum was compromised and in effort to reverse transactions the organization broke off from the original chain
