That's right, but this offered refund smells fishy if they can't keep their word that they will deliver all Batch 3 machines during the next 2 weeks (one more week to go). They gave us 2 days to decide to refund, and it felt like " Hey you can get your money back, but think twice because we will send your machine out NOW(next two weeks)! That's the reason why we will not accept any refund after these two days". Sound for very similar to they statement with that they sold Batch 3 "Hey actually we don't want to sell any machines but we will do it for you as last chance to get a machine. The only condition is that you need to pay 4 times more, but hey don't be worry that's a fair price based on the ROI!". It's like putting a gun at your head and ask you to make a decision, it's clear that nobody was forced to order, but why people did? It's easy, they used peoples trust for being the first one started shipping asics, so people tend to believe their statements as they think these are the trustful capable guys. However, for me it looks like a very smart business strategy to get as rich as possible by the easiest way possible. People asking why they don't mined by them self, why they don't stopped delivering? Follow the money and you get the answers, they took money from Batch 1# to finance their operation, maybe it wasn't even enough to cover all cost to deliver all B1 machines. So what to do in that situation? Just open a new sales to refinance your operation, so they started to sell B2 and shipped B1 slowly. How to maximize profits? Just keep mining with the machines as long as possible. I'm quite sure that at the time after sales of B2, including their mining operation, they already had a good  profitable business, but that was not enough. Again how a company could increase the profits as much as possible? Just sell more with a higher price as long the lack of competition allows it, if and when you deliver is not  important, just collect as much cash as possible. So they started to sell B3 and their chips, at this point they got the most profit out of this business as possible. The great thing is that they don't  need to fear any legal action, so it's legit (BitSyncom is still a US company, not Chinese)! They used the trust gained by being the first ones to get as much cash as possible over the time. This shows me their real face, but cash rules, so they could be successful on the long term. History shows us that people that are able to sell things out of nothing, can become big companies (e.g. Bill Gates and his first deal with IBM, he sold something he didn't had, and was the first one that achieve a license based profit from software. Rockefeller made his first big deal with Vanderbilt about an amount of oil that he was not able to sell/produce at the time the deal was made). These people used strategies to get the best conditions for a deal, even they were clear that they are not able to fulfill it at that time. The big difference between these guys and BitSyncom is that they made deals with other companies and BitSyncom is using us as bakers. However let's see how this will end for us, Yifu is already a rich man.
