"So, if you buy 1 board for 6 BTC, it will pay for itself in just 65 days. Yes, I know, difficulty will adjust and so forth, but still it should be a very good ROI."My 5 month projections indicate that in 5 months I will have ~3-3.5BTC gained from purchasing one of these if it is delivered tomorrow. My estimates are based on a total network hashrate of ~500TH/s by August end and some generously small difficulty changes until the beginning of June. I do all my calculations in a spreadsheet and do them as per-target-period estimates for greater accuracy.
Therefore, in my opinion, this statement is misleading. Difficulty adjusting and so forth is much more relevant now.
I am still interested in a single unit but can only offer 4BTC plus shipping to Canada. I am interested in this more as a hobby project since I never got past GPU mining but don't want to be out the 4BTC for anything past the end of this year. I'd do escrow but if you can have a couple people vouch for you, I would do a direct pre-payment since you already seem trustworthy.
I don't want to waste space in the auction thread with this if you have better offers. PM me if you find you are interested.Otherwise, any pointers to less expensive FPGAs around the 200MH/s - 400MH/s range would be hot
I've been trying to get my hands on something just to play with and set up.
