So i have been bittin by the bitcoin bug also. Im fairly new to this and of course i have made my mistakes in jumping on some bad ideas.
I live in NYC in a Coop (its like a condo with electricity included with my maintenance) so power is never an issue for me. Summer time i usually have the AC on 24x7. After i started reading about bitcoin and electricity not being a factor for me i decided to start the easy way and buy a BFL Jalapeno. I did get a good deal and got a 10gh for around $250 on Craigslist. (ebay has them going over $800 right now). But i wanted more so i decided to read more on it and started to scrypt mine. I got 2 asus R9 270's over clocked and doing over 900 mhs. But the fans blowing on them is getting a little noisy.(AC on the winter makes it too cold in my apt... lol.) Im now thinking of trading them all in to get a antminer s1. And if that goes well ill purchase some more.
I guess my question is, if you didnt have to pay for power what would you build to generate some profitable bitcoins?
Probably a KNC miner (if you can get one at a good price) or an Antminer S1. The Avalon's put out a ton of heat and consume a lot of amps, even though you have "free power", your circuits are going to be limited to 15 amps for standard outlets and 20 amps for kitchen appliances, which means if you place too many amps (watts / 120), your going to pop your breaker. You also have to consider the heat, right now it's winter in NY, so probably not a big deal, but in the summer you could be dealing with a big issue when your AC kicks on.
Avalon3 1TH/s or A1 is lower power comsuption now.
