These kind of increases only caused by speculations. It is not possible other way. They probably burnt coins to help other holders. So its pumped as hell in one day! Beware. This is crypto.
The whole crypto market is 99% a speculation
Even before the pump aeron had around 6 mln $ of 24h volume (now it is over 400$ mln but was over 600$ mln at the top of the pump). It seems pretty hard to pump a common shitcoin like that. I haven't checked that but I suppose that the pump should be connected with some news / rumours about the project.
