14nm need 24million usd to initial batch, how can they sustain with this huge RD expense, and their also admin their hardware deduct value quickly, so again they shoot on their foot twice again,
Where are you getting 24m/usd? They are their own R&D team. They've maintained a 90% profit margin on their equipment from day 1 in 2013. I think they can manage to keep their business model intact and still scrape money from people.
how do they convence bank to invest them?
Banks don't have a problem with them, I would wager. They've been able to purchase a lot of land and equipment and lease the same. Banks clearly have no issue with them. If anything, banks are encouraging their behaviour.
How could they convence people to order their miner again?
By saying "we have a preorder opening up", and people flock to it. Also, you're forgetting that a significant growing number of purchases are coming from businesses and entities, not individuals.
They can save themselves, easy way to do is just ship their miner from their datahall to customers,
My recomendstion for them, just hire some experienced smart second hand car dealer to help them empty their aged datahall and storage, then they could squritch more cash, and also made some smart strategy to avoid them shoot on own foot and their customer again.
I have this weird feeling that they're doing ok by themselves, and are more interested in making sure they get more money, than the consumer.
