eventually, they will probably have to either borrow money or do a preorder to start producing these units in bulk.
If you're asking if we can afford our entire gen3 planned capacity without injecting more funds via additional investment or pre-selling mining capacity to accredited investors, the answer is no.
The same goes for every other company in the space.
For the last time, since you seems to have difficulties in understanding: we'll not sell our gen3 products to consumers without proving the technology first. Afterwards, we might, but then it won't be pre-ordering. It might be selling by batches.
So tldr your current business model / situation can not support generation 3 without preordering (/ preordering under another name) or some miracle investment. Under no circumstances could those statements EVER qualify you for running a business model that can get by selling purely out of hand.
