Definitley reinvest it, in an Ether backed token!

Why? Many tokens are backed against Ether, meaning they still benefit from the price increase in Ether when you change them back to Fiat.

For example I would suggest Oyster Pearl (PRL), it made massive gains during the week, and still has potential for 5-10x in next couple months.
Better yet, it also benefited from the price increase ether saw during the last week.
