I do not expect anything good from the fact that the Rothschilds and the like come to the crypto-currency market. Perhaps the fall in prices in December-January due to their actions. They made an unfair Fiat system and now want to destroy or subdue cryptocurrencies. That's bad news.
Completely agree that rich can influence badly cryptomarkets making speculations, pump and dump schemes but it also can be some private blockchain for their own transactions that will not pretend to compete or damage other cryptocurrencies or coins of some projects. Maybe this will be just a project for the rich that will not concern others.
