again. I don't know. you don't known. the real btc/bth to dollar offer and supply is not transparent. miner can move either way in any second. I don't follow all of the public groups. and there are mostly private big miners now anyway. you might be right on the reason. only the exchange knows. the trick is that the dollar to btc is a known value for them only.
