Ok, guys. I do not want to be party pooper or anything, but this site
http://mining.thegenesisblock.com/ draws rather depressing picture.
Please, correct me if I'm wrong, but. Lets say, you had $50,000 (yes, fifty thousand united states dollars) laying around. Either in BTC or USD (maybe you ordered avalons and they all came in in april, or maybe you just have stack of cash that you have no idea what to do with it) You go ahead and buy 7 KNC jupiters. That puts you at 2,800,000mega hash per second. Let's say you bought 3 avalons from batch 1. so, now you have 3TH/s. Many think wow, that would be awesome speed or something. Not so fast. Even if KNC delivers ontime, difficulty will be around 232 million, according to
http://mining.thegenesisblock.com/ so that fancy farm won't even break even first month. Some people said before (during avalon batch 2 drama) that it doesn't have to be ROI in first month. Well true. However, this is getting large.
All this needs to be housed somehow. 9000w will run you at cheapest $0.07/kWh (cheapest rate in USA that I know of) will cost around $500 or so to run the farm and that is without A/C and A/C is a must. 9000watts is around 30000BTU. So you'd need at least 40000BTU A/C or so. THey are huge air conditioners, with boxes outside and consume something like 6000Watts. 15000watt total. That's about 700 dollars worth of electricity every month... So, what would be the point to mine in this situation? Or maybe I'm raving, Calculations are retarded. So please, correct me. Prove I'm raving
However, even without electricity/cooling costs it doesn't look too promising. Difficulty will be up, why even bother with miners? Just buy coins directly or something...
