Hi group, we are considering purchasing CoinCraft hardware, but after reading these posts i'm really in doubt, see here http://www.clickon.ch/blog/bitmine-ch-coincraft-miners/. The miners look good, as i understand people get decent support if something goes wrong, the refunding is however a difficult endeavour. The question is - can we trust Bitmine.ch as our business partner, or better look somewhere else? Your thoughts are welcome.
The miners are overpriced (at least from what they are offering the public) and have high/bad power consumption. If you are ordering in bulk, you can probably get better deals from other hardware venders who have less obsolete equipment. Aside from that, the company is cash poor and can't realistically give refunds if something does go wrong. Plus they are ethically questionable.
I'd look somewhere else. S3s from Bitmain use 3/4ths to 1/2 the wattage per ghash and cost about 90 cents per ghash. If they are offering you less than 75 or so cents per ghash with A1s(including power supply), it might be worth using Bitmine's older equipment. Make sure you cover your back in dealing with them, though. Try to hold money in escrow and use lawyers to write contracts.
