Nice the dude who took over 70% of the hashrate is gone! I have an idea in the future on a cpu coin limiting the max hashrate of the network. Does a network even really need over say 200khash to work? We could make a coin that stops giving rewards if the hashrate gets over 200khash. Small independent miners who are spending pennies a day mining in electricity would be able to keep mining wheras big assholes and pools wouldn't be able to survive mining it...power to the little people.
I think that was a botnet as it was showing around 2000 miners and now it's just 200 so definitely it was botnet
Yup you are to the point. It really feels bad when you have little hash and people come with contract like nicehash and make sure to create hell for small miners.
For mining with CPU, a botnet is easy to implement, some hackers by controlling the personal computer, in the early stages of the hash, this kind of behavior is deadly, it left now, we are very happy.
