@1: They do not need to.. however most attacks do have this done, as they need to outrace the main blockchain to be successful! As I said before, it is possible to slow boat the system but a "slow-boat" style attack is much more noticeable.

@2: Plenty of "What ifs" in life, yes this doesn't protect us from every conceivable scenario, but it does stop some, you have to give it that.

@3: That will only be the case in the event of a multipronged 51% attack, which I'm fairly certain would be fatal if those "legit miners" were not cut off for 4 hours anyways. IMO It's like saying why wear a bulletproof vest when it cant protect you from an RPG?

Attention is good for our market right now.. I realize the optimal solution is to do things quietly, however right now there is plenty of attention on genuinely shitcoins that could be on GoldCoin.
