Sure, nobody could have anticipated something like this happening and nobody can realistically see the future and take choices based on it, but since we are talking about a centralized platform with a native token, it catches my attention this sudden increase in price could have been planned to some whales and insider to profit based on privileged knowledge or information, you know.
For example, let us imagine and the Fun token was in their previous state of low value and sinking further, but someone from within the team of development of the casino tells you about the new features they are going to release and the roadmap they are going to implement to get back the trust of gamblers. That would probably prompt you to get a serious stack of tokens and wait for the pump to come. I have no proof something like that happened in this case, but someone within the team could have taken advantage of all this situation to pocket a lot of money from inside trading.
