At block 1,000,000 on October 12th, 2016, snapshotting will stop, and you'll be allowed to trade your Ardor tokens in NXT 1.9 in preparation for the launch of the Ardor blockchain.
Does that means that someone can get ardors on October 12th 2016 at the exchanges without having nxts, or it will be something like asset trading on the NXT 1.9 blockchain? Sorry for the question ,but I am new to nxt.
After October 12th everyone will receive assets that represent Ardor tokens, they can be freely traded on the Nxt Asset Exchange. Later they can be converted to real Ardor Tokens. I don't know if the assets will be available on exchanges, that is not mentioned yet. Could be a possibility.
