Yes I know but that was around July 14 when the snapshot period began. But it lasts until October 12th, so more people will probably buy until that to get a hold of Ardor early.

They stock up for NXT, so that they can buy Ardor when the asset will become available as a token. You need to have NXT to get Ardor early, and they will get Ardor tokens as that will be the gateway to the Ardor blockchain.
