I met a woman last year who I'm pretty sure was cashing out for a hack of a New Zealand exchange.. she didn't say it explicitly but she was getting 10% to cash out on Huobi for a group of IT students in Guangzhou China. One of the guys was an american and I think it was his job to find people to cash out. They were doing about 150k USD a week, and she was pretty sure there were others doing the same thing. he told her they found a way to get free ETH. I sent a message to the exchange that got hacked Cryptopia or something but they never got back to me
