Well if you can get someone to give you 7000 dollars for a device that generates 50 dollars a day and dropping rapidly every 3 days, more power to you. I wish I was that good a salesman! Good luck with the sale
If you forget about FIAT values of Bitcoin and look at it like this
Right now its about 10.8
BTCOn best estimates here
http://poolpicker.eu/table you will earn roughly 0.0011 per MHS per day for now
Which is about 0.1 per day @ 90MHS
With no power costs and no rise its about 108 days to mine back what you spent
Add power and rising difficulty you would be looking at 150-160days
Which is pretty much exactly the same as you would get with any other miner at the moment
If I had $7000 I would but 10.8BTC but some people like to mine
No need to make stupid offers like $2000 seem legitimate though
I'm not trying to start a debate with you in this guy's sales thread. For one thing, I at least made an offer. In any case though there is 0 chance this thing ever mines 7000 dollars or 10.76btc. Yes, you're right, it makes about 0.0011 per Mh/s per day which would ROI in 108 days if difficulty did not go up. Look at the chart you posted. A month ago though the return was twice as much, 0.002 per. A month before that it was 0.004-0.005. The revenue generated by this thing whether you measure it in dollars or bitcoins is dropping 2% per day every day.
So I'll tell you what. If you are really that confident this thing will generate 10.76 bitcoins, but don't have the 10.76 bitcoins to purchase it, I'll wager any amount of bitcoins you DO have that it does not return 7000 in not 108 days or even 160 days, 180 days. I'll let you pick any benchmark (publicly available multipool that posts its stats) and I'll let you pick any reputable escrow to hold the money. I'll even give you 3-1 odds (3 of my bitcoins wagered for every one of yours). Or I'll give you even money that this thing doesn't even generate half that in 180 days.
