My opinion is that they got overly excited because of the high demand the last few months- maybe the price will cool off the demand and they will come to their senses.
Why is there no manufacturer in US?:/ all of a sudden crowd funding looks like a good idea - God knows we have the brain power and resources - all we need is a good plan and financial backing.
It's all a semiconductor design challenge. Crowdfunding might get a nice design, but you need Wafer Fabs to do this. As for doing this in the US we left this business to Taiwan years ago. They are better than we are at it - and will be for the foreseeable future. The Chinese arent very good at it either...every S9 Bitmain chip, as far as I understand, comes from TSMC, which is based in Taiwan.
