blake2s has been a warzone. What the heckin heck. As soon as a pool's hashrate goes up. It's like somebody in another pool or something hits overdrive and takes us up to 100k difficulty. It's instant too, i don't understand.
Maybe someone is renting all the blake2s power for short times. Or one of the solo miners is hopping on and off. I know 1 solo miner tried to hit one of the algos all at once and slowed down the blockchain for a bit a week ago. 70 GPU's I think.
In chat I have seen 100-500k being possible numbers for masternodes. Its a long time away, but I don't see why not try mining that amount for a long term HODL.
