I'm thinking about purchasing an antminer s5 does anyone know how good they are.

so it's about .10-.11 i believe around here so what would you estimate on how much hash rate i would need to start making decent profit?

Hi, So i have an antminer s3, but i haven't been making profit fast how many do i need to make a profit faster than what i am now?

ok thank you so much.

so it will always have memory then?

Hi, My Antminer s3 says i only has 66% memory left.  So i was just wondering what happens when its memory is full what do i do then.
