There are two methods to buy DLUX tokens. There is a Decentralized Exchange at dlux.io/dex and the current price of tokens is in the 1 DLUX for .4 HIVE range. The other option is sending HIVE to robotolux, but the ICO is set at 1:1 for the whole round(it may go up but is design to never be lower than 1:1 to insure that inflation via ICO is only happening with significant interest in the project). DLUX is not a Hive Engine token as well. There is a wallet at dlux.io as well to manage your tokens via Hive-Keychain(much like Hive Engine)
