Forks are in my opinion just exploring the popularity of the main coin in order to profit themselves. The team behind BTC Cash for example new that people would be attracted to the benefits they offer, and instead of making a similar network or blockchain themselves they simply decided to fork BTC, which is bad in itself but harms the entire system if you ask me. As it seems with the latest fork they have profited massively, BCH cash is trading at about twenty billion right now which simply means that other people will see that, and will want to do something similar, so don't wonder if within the next year we'll be seeing five or even ten potential forks or forked versions of Bitcoin, it's just the profit that these projects are after imo.
