In the BitcoinCash economy, the drivers are notably different, and the complexity of the models tends to be higher. The fact that the independent variables are different than those that drive BTC returns speaks for the structurally different constitution of both economies: users of different services both consume investment information and have a preference to trade in different exchanges, such as Korea-based Bithumb. Some are even different people, as demonstrated by the fact that they seek information in Yahoo and social validation in Facebook, not in Yandex and vKontakte. The higher information content of higher complexity models may also induce over-fitting in the presence of noise.
