I do not believe that the future forks of Bitcoin can generate any currency of value. They are just a tool to further strengthen the price of Bitcoin. However it ends up disrupting the market.
Fork ia unending process, it is basically a help for bitcoin to be stabilized. Forks are meant to fix bugs and errors, in this way bitcoin is developed and features are made better. Forks also gives user free coin, which serve as an additional profit. Bitcoin fork basically a help to determine flaws and things to develop. People who are not for bitcoin are determined, and we are able to determine the stability of bitcoin because of the attempt to compete with it.
