There is very less probability of this happening. However, one thin has surprised me for sure. BCH was showing positive returns recently (24 hours period) when all other coins were red (including bitcoins). This is the sign of a good coin and if it continues to show similar behavior in future, I am going to invest some money there as well. So far I had invested mainly in bitcoins and ripple only. In my opinion only ehtereum has the capability to cross bitcoins in future.
