You can get like 200% margin on selling GPUs to PRC smugglers in Taiwan. It's a very busy industry with lots of players so the margin gets spread around. Recently a big ring of them was busted and sent to prison here so most people try to have as many middlemen between them and the guy that puts it on the boat as possible, because apparently the prison sentence is quite long.

I had someone offer me 10x whatever I bought for (not even MSRP just whatever I paid) for "as many GPUs as I could get my hands on." I asked hundreds? Yeah. Thousands? "Can you get us thousands???" It's fuckin nutty.
