Though it is fun, nowadays the existence of different gambling sites have slowed down the interest over these kind of betting.
Prediction via pool betting is now trending on defi like on Pancakeswap prediction contest that let user bet on the price of BNB. The multiplier of the bet will depends on the difference between the difference of the prize pool of each side. This game idea is with the prediction betting that you mention earlier. Many dapps are already creating different version of this game. Maybe on typical casino, This kind of game doesn't in demand anymore.
That does not really seem like a game in which people should be interested, and the reason for that is that we need to have a very strong distinction between gambling and trading, gambling is supposed to be an activity that we do for fun, and as such there should not be any problem with losing a little bit of money each time we play, but when it comes to investing then everything should be about making profits, but at least to me the games that you are describing are trying to mix the two making many people believe that they can do both, to obtain profits and get some fun, when most of the time this is simply not possible.
I have seen in freebitco that they still have their regular betting lines regarding price prediction of btc, eth & fun token.
So maybe, this kind of betting doesn't attract anymore in some gambling sites, but I believe freebitco is still gaining a lot of bettors on this aspect.
I also believe, it is how the platform presents their betting lines here or promotional incentives offered to their players to sustain their interest.
They need to add other games or features aside from the prediction betting lines, because gamblers need to see or play other games while waiting for their results.
