Hello,

I live in the US in an area with cheap hydro power (.02 /kwh) and cheap warehouse space to rent. I'm wondering if you all might have some input on the following:

1. Any estimates on how long 16nm chips will be relevant for?

2. For 50-100 rigs how time consuming is management and upkeep? Will have two people available nights and weekends.

3. I'm considering Canaan's AvalonMiner 741 - any other rigs you'd suggest I look at instead (Won't buy Bitmain for ideological reasons).

4. How long would would you mine with any given hardware before trying to resell it? Or would you work the hardware until dead / no longer profitable?

5. Starting on the smaller end of the scale how best to grow the operation other than re-investing profits?

6. Lastly, would you even bother? Why or why not?
