My last slave was also a money slave and so is the one I have now. It was on their request so it's nothing I demand at all. It requires extreme financial responsibility, which I have. Not being a poor guy also helps.

My slave gives me what she earns and begs me for money when she needs it. I'll usually say yes. I use my judgement, which seems to work fine. My job as a Master isn't to make my slaves life more complicated, but on the contrary, easier. I am a very generous person so I doubt she feels used in a bad way.

My advice is that if you want to be a money slave. Give it to somebody who doesn't actually need it, or you might end up just getting used for the money.
