I'd like to see the process take place, and if the market kills off bitcoin cash, so the better.
Here's my logic:
In the beginning of my country (USA), we had multiple currencies floating around the colonies as banks, trading houses, and even gold purveyors competed for currency control. The people quickly figured out which currencies worked and which were bad; very similar to crypto-currencies.
The results, as you can imagine, was the killing off of 'merchant' currencies and the rise of gold/silver.
During our revolution we started printing paper money, which led to inflation and black markets in goods. After the war, the people quickly killed off the paper money and went back to sound money.
The point: Crypto is like America in the 1760's.
If bitcoin cash is crap, we'll kill it off.
