The suggestion is to mindlessly grab in the first stage; if you grab it, you earn! Of course, the earlier you grab the price of the joint curve in the first stage, the cheaper it is. As for the second stage, it's already at the highest price, so just sell mindlessly! Of course, it doesn't rule out the possibility of higher prices after going to Alpha, which is a bit of a gamble. If you want certainty, then sell in the second stage.
