I would definitely buy ETH, XMR, OMG, ZIL ... and also a little ADA, because if the creator keeps his promise, this coin will give a lot of X.
ETH, XMR and OMG are still a good choice while the remain two coins seems not to have some wave makng potential. However, I will advise you not to choose coin base on the promised made by the project owner cause it may make you detest the coin or make huge lost in the future instead choose coin base on there historical data, utility, concept, community support level and liquidity.
