It's not like my hashing rate is rising, it's network block generation speed is low today which causes pie chart to look more scary than usual.

Create a good pool, make a better offer to bitcoin miners and they may switch. That's how competition works.

Why not create more ? There will be a LOT of new miners soon.

Don't make me say my opinion on bitcoin security for the fourth time
