Actually this will help the network long term but it's getting a little tiresome, let's see how the next fork goes and if there are any upcoming news with Casper. The price doesn't seem to be dropping below $10 anytime soon even with no news and regular attacks.
If any coin is to succeed in the long term it needs to be tested for safety and resilience. Trial by fire so to speak. So I'm actually glad that people are performing attacks, it's the only way to find out if the technology stands to survive or not on a larger scale.
