It was not postponed, it was scheduled. The Utrust team had made an announcement about changing the date and ICO structure way back month ago. They believe that if they will follow the old system, whales will definitely snatch the early stage ICO and leave the normal investors with the last stage of ICO(whales getting the cheaper token and normal investors the higher priced one). Aside from that announcing it a month before the ICO will enable investors to gather fund before the set date.
Which whales you mean? On pre-sale or ICO? They ll have fixed price during ICO - 0.065$ per token.
