I bought district0x. But I still have some questions. How to put my tokens on market and sell It?
You will need to wait until the ICO is over and the team behind the project start asking exchanges to add their token. Until them, you will need to find someone to do P2P or just hold it. They will probably release informations about this issue in their blog[1].

This probably means that the tokens that weren't sold during the ICO stage will be "destroyed". I don't think you will have to do anything.
But I'm not 100% sure since there could be a new technology that the project is implementing.
