We have seen the hacking attack of reportedly 60M USD from Bitfinex and the attack of the DAO for reportedly around double that amount.
But after both attacks we have seen two very different things happen.
In the case of the Bitfinex attack there isn't even the slightest suggestion that some sort of "hard fork" would be offered by the Bitcoin Core developers (so they are just going to have to wear their loss for their mistake) but in the case of Ethereum we have now ended up in a "fork war" with ETH vs. ETC (and ironically ETC is actually the "original" code with ETH now being a fork).
Opinions?
ETC is severely damaged forever as a project, and the reputation of its leader, Vitalik Buterin, it's also perpetually damaged after he tried to stop exchanges, after he bailed out investors with a very questionable hardfork, and after the hard fork due it being rushed presents huge problems like the replay attack.
The only reason ETC is not higher than ETH is because ETH has the inertia of being the bigger chain, but eventually the tide will change and ETC will take over. ETH fundamentals are doomed.
