Bitcoin Cash mining is highly centralized. Just check out the image above. If we combine the hash power of Antpool, ViaBTC, and BTC.com (Roger Ver and Jihan Wus mining pools) which makes more than 50% hash power. These two people can do a 51% attack anytime they want. Bitcoin Cash also has only 1,200 nodes, with a lot of them running on AWS and bought by the main proponents of Bitcoin cash.
