( Had three ports that would not accept any Erupter USB that was plugged into it, but worked fine in any other slot. *shrugs* )

OMG .Fools and their money! When this was announced difficultly was under 10m and network hashrate under 80t/h. Now you've got them it's 12m (+20%) and network hashrate is 100t/h+ . In under 3 days difficulty will hit 14.4m. So thats a 44% increase in diffuclty in 5 weeks, around the 30% + a month I predicted.

5 weeks ago each of these would have made you $1.84 a day for the first week. Now you are only making $1.51 a day and this will drop to $1.27 a day in under 3 days when difficulty hits 14.4m.

So lets forecast from there shall we! Starting @ 0.0104 BTC and $1.27 profit a day for the first 10 days. 1 month profit $38. 3 month profit $90. 1 year profit $155!

May I remind you that BTC has gone up only $10 in the last month. And you have paid $220 for each of these last month plus the 1/9th cost of the powered USB hubs and fans plus the cost of all the shipping and customs charges of the USB miners and hubs and fans.

And looking further ahead after 2 whole years of mining with $0.01 per day powercosts for each USB you will have only made $158. Yep, @ 30% increase a month you will make a whole $3 in the second year. Buy the end of year three these will not earn enough BTC to cover their power use!

You lot will have to pray (and hard) that BTC difficulty slows it's current 30% a month increase or that $/BTC steadily rises to over $250 in the next few years or you will never make a ROI.

To big a gamble to stake way over $12k on. Good luck though, I admire your balls, and I thought I was risky putting $900 into 3 x BFL 5 g/h miners (15G/H) to arrive this side of Xmas.
