according to this old thread
https://bitcointalk.org/index.php?topic=10860.0, the usage is very low around 2mb per hour, you can build a huge farm and still consume very low
bandwidth is never a problem with mining, initial investment, consumption/cooling and space are the real problem
thanks for this., i always wondered how much bandwidth does the ASIC uses, at my place internet goes down frequently.
i wonder what hapens when internet goes down, does the ASIC keeps mining or just goes haywire ?
obviously it can't mine, here everythign function with internet if you have no connection there is no mining and no bitcoin
but the good thing is that you can have your usb stick and connect just fine with it when connection go down from ISP
