Bitcoin Cash will hopefully do just fine. As per Satoshis design. If it doesn't, we'll have to adjust without breaking it.

(BCash is actually a different payment method used in Brazil and the use of that term has simply been encouraged by r/Bitcoin redditors amongst others as an opportunistic disinformation campaign against Bitcoin Cash. The justification mostly used is that Bitcoin Cash is an attack on Bitcoin as a "brand", when Bitcoin is in fact an entire design defined by Satoshi in the white paper and explained in forum posts)
