The dollar blue is an unregulated illegal currency exchange. Those who have dollars love it and will continue to take advantage, however it is not rational and often subject to illicit manipulation by govt and by the larger exchange houses. 10 dollars is something of a watermark and once we start to see those levels behind the scenes efforts will be made to make the unofficial value drop.
Personally, I think the peso might devalue too around 8USD, that will be attractive for inward investors and the hope, and it is only a hope, is that the official rate might synchronise to some extent. If the spread was inside 10% you would see more official tourist dollars back into the economy.
All above the is aspirational for the govt, but bottom line is that the motivations for the movement of the blue market are not always self evident. Sometimes, of course, they are such as upcoming aguinaldo (people use it to buy USD, value rises) and vacation season (all off to miami, dollar demand rises).
