Now you know why bitmine.ch was actually delayed... the Chinese manufacture that was actually making the chip, decided they wanted the first batch for themselves... Why do you think they offered to manufacture the chips for them. (I bet it is Avalon's same factory hiding under a fake name. lol.)
Mysteriously, 1 months of production is "held-back" at the MFG's... They tell Bitmine.ch, Oops, we had a bad run, your chips are coming soon... BTW, mind if we see your schematics for your boards, while you wait for us to make your chips for you... again...
This is why you NEVER go that path. No-one has ever had good results going that path.
Don't tell them it is an ASIC/BTC chip design... tell them it is just an advanced multi-linked 555-timer with time-slip calculations for measuring the speed of snow-fall, or some other useless thing they won't be tempted to steal for themselves. After-all, they do MFG the chips... I am sure they will figure out how to use it, if they know what it actually is. Not hard to throw them off, with dead-zones in the chip that actually do nothing, and consume little space.
The govt had people all around the world building things, that they didn't know what they were. Just gave them plans, and said build this... (They didn't even know they were building a massive floating bridge and barge, designed to reach the coast from miles away. They were even forced to sink the created pieces, so no-one knew that they were being made, until they were all made and ready to use. Then they floated-up and were sent to war. lol. Failed though... But the production idea worked great!)
When you develop covert things, you need to be covert about it. When you are that open, you just set yourself up for disaster, because those who produce ti for you, already have a big advantage as they are not paying crazy overpriced prices for their own production, like they charge you. That, and they are the ones producing, so you are guaranteed to get anything you asked for, after they take what they want for themselves.
Lesson learned, new models with new technology will be out soon... Hopefully a lot more covert in nature, in the production phase.
LOL, do the "apple" approach... program in bugs, that cause failure, only you have the "correction-chips" and "correction-code" for it to operate normally. Problem thwarted.
