What I don't understand: I got the reply that space is fully exhausted for own miners but I could order one with them directly. As soon as I buy my tokens, I should be able to send my own miners? Can anybody answer this?
If so, what would be the problem to order directly on bitmain? What about installing these devices, potential extra cords which might not be part of bitmain's delivery, customs tax etc. - would giga-watt take care of this and eventually deploy this machine?
You can send your own miners. Afaik there is like a $20 setup fee. Also I think they do some sort of basic maintenance/upkeep on the miners. You have to pay for shipping/customs/taxes etc. They will deploy the machine for you.
They are opening more facilities and they won't issue you your tokens until there is space for them. So by the time you get your tokens I assume there should be space for your miner too.
