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...
What consequences? Do you have any example, since there were lots of attacks lately?
