BTC is currently charging $140,000 every 10 to 15 minutes to store less than a single Floppy Disk of data across 10,000 nodes. BCH does the same thing for $20, across 4,000 nodes.

BCH does the same thing for $20.

Edit: Correction: BCH does the same thing for $20, across 4,000 1,000 nodes. Thank you /u/TraderCryptoCoon for source. For an apples-to-apples comparison, it looks like BCH will need to charge $200 per MB of block space with 10,000-node redundancy. You're still going to get a lot of change back for your $140K.
