Well, I noticed yesterday that the going offer price for used S1's was
BTC0.5 - but Bitmain have lowered their prices again today, and will probably do so again tomorrow, and the next day......
However, I would still be willing to offer
BTC0.5 per S1 without PSU, incl. postage as long as the Bitmain price remains the same (currently
BTC0.619) & provided the units were 100% working with all "zeros" on the chips & had no more than 1% HW error rate each. I would buy a small amount first - if the deal went smoothly & the units are OK I might be interested in more, depending on price again of course
Diff goes up, prices come down - this is the Bitcoin way........
Feel free to PM me if you like.
Peace
