from what I remember the Bitcoin core folks wouldn’t increase the block size which led to slow expensice transactions on chain. Bitcoin cash forked to have cheap fast transactions on chain. Bitcoin core then created the off chain “lightning network” to solve their broken on-chain problem. so it didn’t really seem to add much to the equation. some of us basically view bitcoin::bitcoin-cash as reddit::lemmy I guess as an analogy. or maybe something like monero is better instead
