Well, with such a profitable miner that is capable of switching algos and making a large amount of money per day, they have no reason to sell it overseas with added electrical cost when they can sell the miner to those in China. It's sad but true, they might even be mining with it themselves.
This is what I said about the giveaway price of the big iBelink, why sell it if in two weeks or less it has paid for the cost price of the components, they dont need to sell it at that price and could have easily asked 2x or 3x and still would be attractive, or more believable.
