i have question

can i sell some of my minecraft accounts in here is that allowed or not please tell me because i need to know

Generally, the sale of a minecraft account is legal, there are different sites on which you can buy a minecraft premium / sell. Only people look like trusted people than the first better ones

You can sell them in the marketplace. It's not disallowed

Yea as Zenith said most forums have a marketplace section where you can sell user accounts/services etc. Have a look over there and find the correct category for it.

As everyone has already reported, conduct a check in the market area of the forum, I believe that directly through a topic can not. Let's look at the rules.

Yes, why not? This is your property for which you paid. Same as with a car. You bought a car - you got bored - you sell it
