I'm thinking of waiting and just pick off some S7's for 600-800$ in a month or two. The difficulty is still climbing and the latest S7 batches are inferior in efficiency to the latest, so i don't really see the S7's being worth all that much before long. I hope those who bought at 2k+ got their 1k+ return already.
I do not remember so expensive S7 at 2k+

BTC value has went up aswell. Some bought when it had a lower value. So if they waited it would have been better there aswell. But we had no way of knowing going from like 230 to 400 or so would happen that soon. Best bargin was when it hit around 500 that one day as price was still varible I think they got best price (could have changed after drop).
Now it seems they do a fixed price in BTC so value of BTC is not near as much of a factor.
