Agreed. It is better to be constructive than to start knocking holes in the boat we are all on. Bitcoin and cryptos are about psychology in terms of widespread public adoption. If people think their Bitcoin can be "killed" by some government, they won't trust it or invest in it. Almost nobody will care or get what machines or algorithms secure anything, nor understand it, just more ammo to use against Bitcoin and all Alts.
Ditto. Auroracoin has gained so much attention that it will be everyone's loss to see it fail by some attack. Every government will get ammo to be against crypros. And normal people, who have only heard of these from nerdy friends will simply reject it. Failing the entire crypto currency movement.
