The main idea behind BCH is that they are going to allow as many transactions as possible to allow micro-transactions to take place for a low fee.
bitcoin cash is already charging fee and free transactions are impossible on that chain because they removed the possibility of it, just like how bitcoin did! but with the difference that bitcoin blocks are full but BCH blocks are completely empty! so they are overcharging for fees no matter how much it is.
If BCH is going to become centralized, why not just use a fee-less centralized system with off-chain transactions.
https://www.fliptopay.com/ . I noticed this site. Basically you transfer bitcoin to a centralized wallet. From there you have virtual bitcoin and can convert to USD or Euros. There you can use the currency at any android pay store. Note this is not fee-less, but it easily could have been. blockchain.info wallet is basically off-chain. All transactions on these type of sites, between its users and stores, are off-chain, and take zero space or fees on the chain. Yet they work instantaneously.
if you want to use a centralized system then why use bitcoin at all? use other centralized ones that use fiat. for example Paypal, Visa,... are good enough. you don't need to trust a shady website that is unknown!
