Why would people attack this coin?
Do they target all scrypt coins and try to make double spend attacks?
Or is it noble that get a special treatment for some reason?
I think we have some enemies, probably the same people who are involved in the scam coins and see us as a threat.
My opinion is that we should stay with scrypt, inevitably this will happen with any algo. The only way to not have this happen is to constantly switch algos, which is a crap idea.
I think there will only be a temporary spare of attacks, then the "good side" will catch up in terms of hash power.
Hard to say this is an attack, that guy probably wasted a few days mining, maybe he was initially thinking he can get profits here by mining hard.
