Wait wait wait wait, you got 5B1s that printed 32btc a DAY = up to $7000 a DAY, and you're calling them lying scum?
They gave you this money for free, you should be thanking them.
thats totally nonsens. He ordered and paid something he didnt recieve.
Maybe he shouldn't have been so greedy.
Its like if I said I'd give you $800 for free, then turned around and only gave you $500, would you really be complaining? Should you be? No, B1s were a gift, were charity.
Lets suppose I sell you 8 gold coins for 100$ each. In the mean time price jumps to 1000$ each. I send you only 5 and never answer your calls or emails. You are able to sell 5 coins on ebay and make a lot of money, but still you have 3 coins missing.
Is it OK? We had legal agreament, and I faild to deliver.
In my opinion it is called SCAM. You paid for something, and i kept your money AND your gold.
TL DR: OP did not get "$500 for free". Avalon would never develop an ASIC if they did not get financing from investors like OP. He answered the Yifu call, took the risk, send Yifu money, and he should get device he did pay for.
Still TL DR: Most of you are so greedy and jealous that you fail to think clearly.
