was looking to preorder several pallets of A821s to split some back here and try to help bring the pool hash rate up, but total uncertainty about the possibility of being chosen plus $3000-4000 (also uncertain) per unit? At a time when coin prices feel as though they might be headed for a prolonged slide and electric companies are tightening expansion availability and/or making new rules/fees for mining customers.... I'm sure canaan will find plenty of customers, but not me. Not thrilled with having to keep adding S9s, but it seems like the only viable option for now.
