Hello everybody,
I plan to buy a domain name (from godaddy). The question is, if i want to sell the domain name (ex ebay), do i have the right to do it? Do i have the right to do it with as many domain names i want?

Yes. You will be able to do that. That is not forbidden

Thank you for your answer SiberForum! And another question i have is how we sell it? We give u/n and pass to the buyer or there is another way? At ebay for example...

(Sorry for my question but i am new on this subject...)

Yes, you will be the owner of the domain name for the period of registration
