The market is completely unpredictable however when there is an event that you know in advance has the potential of making an asset more valuable then the smarter investors will begin to invest in that asset before the event takes place and if enough of those smart investors do the same then the price is driven up and the investors that are not so smart begin to buy because of the fear of missing out not realizing that most likely they have bought at the top once again and they have no chance of making profits as there is no one else to buy those assets.
