In my opinon here, I'm going to be thinking the only reason that Bitcin / Cryptomarkets don't have prediction markets is cause you're not going to be able to predict these markets, think about it like this -- most of the coins that are big these days are going to be insanely premined already so predictors can only say that these people re going to be able to sell, they don't know when these people are going to make the big move to be able to go and sell. So to put it in short, you really can't predict this market.
Yeah right they can not be predicted, they move as needed, Like the bitcoin is getting higher, it's unpredictable. And prices tomorrow or next year no one will know, they will move as needed
