The pools are certainly not earning more fees due to such incidents. Because the long period of slow blocks and less fees (per hour) now will make up for the short period of more fees (per hour) during the attack. I am therefore puzzled why they would actively invite nicehash attacks by providing a dedicated port just for this centralized service.
so you mean, pools should close nicehash port until the problem is solved?
This would be ideal, as Nicehash is no good for any crypto. It's nothing but a botnet. As for the permanent fix, we are working on the difficulty changes on the main network. We are also updating the node list.
