I am happy to hear the news from Yifu. I feel the tone of this community has a pretty poor attitude towards the engineers that make it all possible, and the people that work hard creating companies doing what they love (which is not sitting around making sure mining rigs have power). I know BFL took a really long time to develop their product, but Avalon has their product developed.

All this talk about making roi... maybe you should power them with an excersice bike instead of paying for overpriced middle America electricity fees. You would have enough time to calm down and make some happy molecules in your brains (these are important). Also if you plan on making real money(over 50k/yr min) by mining you might want to start looking for a real job again, I mine to support the bitcoin currency and to generate a littlte bit of it for myself, I also work 2 jobs and create electronics as a revenue generating hobby.

You must have understood the risk involved when you spent the money on chips... hell their wasn't even a working board design (other than avalons) when I spent my money. You must have seen what went down with BFL before you spent money on pre order chips from Avalon... Im glad I talked my buddy out of dropping $20k on boards from terrahash (dropped $2k instead, put 15k in a hedge and a little liquid). Did you not understand the rise in difficulty that was going to occur? I also didn't put all my eggs in one basket... if you are looking at bitcoin mining hardware as an investment then you should really diversify so you don't get burned.

I just feel the attitude in this room is a bit dark and could use some light. Especially seeing how none of this technology even existed a year ago and you are all complaining how screwed you are to not have the latest and greatest toys.
