So I put together a spreadsheet which predicts whether an order number will fall in the first 10,000, 20,000 or beyond. I've linked to it below.
Currently the cutoff for the first 10,000 is between order 465 and 475. The cutoff for the first 20,000 is between order 515 and 540.
Terrahash Order Tracking100% pure speculation of course. Since NO ONE has any damn clue as to what or how they are handling orders. It's freaking circus for now.
