First I would have a talk with the genie to be sure it's not a trick and I would have to think about the wording of my wish very carefully. But I would ask for money.
I would not ask for a precise amount, I don't want money as something to hold on to, I just want to be able to have the money for what I want without having to worry! Do I want to travel, no problem about paying for a plane ticket an hotel, a rental car and food... I would not go for fancy and expensive anyway... I want to be able to get my family and friends all that they need/want. I don't want to be rich, I just want to have the funds that I need to not to worry about money and not to have people I love worry about money either.
