Not s scam, but here is more info. Coincraft A1 ASIC chips are produced in China in Innosilicon factory according to Bitmine.CH design and produced for Bitmine as ordering party.
http://www.innosilicon.com/Does it mean some worker was stealing or maybe some other way thief(s) obtained them (stealing in shipment?), I'm currently unaware.
However I am aware that each tray is 9x21 meaning one tray has 189 chips, so a thief have stolen approx 10 trays and maybe some extra he/she/they could put in their pockets.
Technobit was regular buyer from Bitmine, as well as AMT.
Yes, I'm quite aware of the connection between AMT, Bitmine and Technobit. AMT sent me a miner to review and to alleviate some fears about their legitimacy. I think they failed in that, as they haven't alleviated MY fears about their legitimacy. However, the beast runs Technobit HEX16B's, and I have followed Technobit pretty much since their founding. They were first to market with an A1 based miner. Well, hashing board, anyway. AMT is still dithering.
But what I was referencing was that the note, when translated, mentioned AMT and Bitmine, but not Technobit. Just found that a bit odd, given that Technobit has more exposure and success than AMT, and probably at this point than Bitmine. Why leave them out if this is Legit? (or perhaps certifiably illegitimate, given the subject...)
The numbers make sense in light of your new data, but why two NEW accounts posting the same "warning" in the AMT and Bitmine thread? I smell fish.
Smells fishy. But those other three NEW accounts (skyfromwell, seeksilence, haevenstar) smell even fishier to me.
Edit
Why Technobit wasn't mentioned? Maybe because Technobit isn't selling 1T miners, and wasn't perceived as a direct competitor.
