I did not buy them. I am operating them for a fee for a friend. Based on the timing, I would say 2 which is unfortunate for him. I wouldn't have bought at that price and I told him that. However, this shouldn't be a competition to prove I made bad decisions. This should be a discussion of facts.
At 2BTC a piece I agree.
Also, I am the pool fee, so even on my own hardware I don't have to worry about that.
Dude, I've been mining since December 2010. I know how to calculate expenses. If you want to discuss potential difficulty, sure, that is guesswork. But I know expenses.
K your 0.2btc return on 18 months plan is too little for my tastes. And a bit too risky considering
Thats based on 10% 11day schedule. How much is shipping on those?
Shipping is free. I'm still not buying at 1BTC, but it is profitable and I will gladly continue to operate for a fee as many as my friend wants to buy.
Personally, I am waiting for a better proposal once AM gets some competition. At the moment, they are the only ones shipping in reasonable times (2-4 days from China to US vs. a 3 month estimated queue at BFL and taking a risk on Avalon's "we will deliver when your rig starts to fill with dust"... oh or KNC's 28nm dream machines). I'm waiting a few more months to see how it all plays out.
The real question is how the heck are you getting a hashspeed of 400 instead of 334? Do tell...
1. Plug it in
2. Start mining
They are likely advertising a hashrate that is based on average imperfection rate and a fair margin of error. All ASIC production has areas where the chip doesn't work properly, so you might only get 90% of the cores in the chip that actually function properly. Either they added too much buffer to their estimate or I got really lucky with all 10 of my miners.
