Network hashrate almost doubled since you posted this, attack could be going at this moment...hope they change algo soon
C'mon guys, I guess you're long enough in crypto to know better.
Yes, that might be power cost for 51% attack, but it's same like claiming it needs only $50 (for a handgun), to get a lot more by robbing a bank.
Double spend is fraudulent activity. Anyone can do it, but they should be prepared for the consequences.
Be serious...
