According to Max Keiser "Bitcoin cash is an alt-coin that has its fans just like many alt-coins. I dont think anyone who uses bitcoins name and applies it to an alt-coin like bitcoin cash does is adhering to acceptable business practices. In other words, bitcoins brand is being stolen by a competitor that calls itself bitcoin cash and this is outright fraud in my opinion,
just like its fraudulent to use Coca-Cola and Nikes name to sell soft drinks or shoes".https://www.cryptocoinsnews.com/max-keiser-bitcoin-to-reach-100000-calls-bitcoin-cash-a-fraud/?ref=coinwisdom.orgloool@MK
