I'm 24 and got my first credit cards a year ago to build my credit, it's at about 680 now after paying them off every month as soon as the statement is posted. Will my credit go down if I start to pay only the "minimum payment required"? I ask because thinking about it I could probably make more with that money than what the interest charges

Good financial advice says it's better to keep cards paid off, but good financial advice also says to let your money make money, so what are your opinions? I would never pay full for a car, so why do it for my cards?
