This week in Crypto Watch, Alan Kohler spoke to Roger Ver, the Chief Executive Officer of Bitcoin.com and the main proselytiser for Bitcoin Cash which is the competitor to Bitcoin. Roger recently tweeted  that "Bitcoin Cash just processed more transactions in a single day than BTC ever has, and the fees stayed at a fraction of a penny." Roger is all about Bitcoin Cash now, and believes it's the one that's going to take over, so Alan spoke to him to find out why.
