Is it safe to pay for MineCraft with a credit card?

I've been dying to get minecraft. But my dad does NOT like to use his credit card to pay for anything I ask him to. I'm serious. It took a whole week for me to get access to the app store after I got my iphone. But I just want to know. Will minecraft (mojang) rip me off? Will it use my dad's credit card for other purposes?

As of right now, about 7, 575, 440 people have bought Minecraft.
None of them have been ripped off by Mojang - they would've been sued by now. I've bought it, and I can tell you it's safe to use your credit card, and it'll be worth it.

My dad also doesn't want, why don't you download Minecraft via Cydia and then install via Installous

It does give Mojang rights to use your creditcard on whatever they want but I'm pretty sure they won't?

I mean, you know Notch, the owner? Right? He's a pretty cool guy and doesn't afraid of anything

ITs completely safe. If it wasn't, then it woulda been warned and not as many people would have bought it, I can tell you from personal experience that its completely safe.
Happy Mining!
