How to change my cracked minecraft skin so that everyone can see it?

My friend got me a minecraft gift card and it says its not valid, so i'm asking how to change the skin on cracked minecraft

Buying the game would probably help.

You can't. To change your skin so everyone can see it you would need to access the skin database which is only accessible if you have a legit account. For as long as you have a cracked version, you can only change so you can see the difference.

A minecraft cracked account can't do that. Mainly, the only thing good about that is that you didn't have to pay for it. If I'm correct, a cracked account is basically useless.
