Whats the difference between regular minecraft accounts and Premium accounts?

I was wondering either to buy a premium or a regular account

Buy premium!

Having crack is not legit

You can change skin

Prestige on nonpremium servers

You can make videos on youtube without hate

Not sure what you mean by "Regular" account. But with premium, you can change your skin, join the premium servers like Hypixel, Mineplex or other servers that you find. Basically that's all for the premium account.

premium minecraft is just the game you bought and non premium is just a demo

Premium account it's the best for play this, non-premium it's a demo, the best servers are premium!

A Premium Minecraft is better. Having a crack is not good for the Game, because the devs lose money.

Most likely, in this case, it means that the regular Minecraft account is just used as in alt and the premium account are able to change your email and whatnot.

Premium accounts are better as you can change the skin, email, and no one else has access to them.

Regular I assume is cracked...
SO obviously premium is better because you can play on many more servers than if you crack Minecraft. You'll also find a lot fewer hackers on more populated servers because at least some Admins and Mods can control the population. If you get banned from cracked, you can always make a new account just like that.

One is legal and the other is not. With the legal one, you have a unique identifier per account. With the cracked version, you can have any ID and GUID ..
