Despite all the obvious benefits of mollywopping the middlemen with P2P money, the thing people can’t seem to handle is the 10 block lock (~20 min delay). I like to tell people it takes a minute to launder Monero so it comes out scrubbed. How do you explain the 10 block lock as a benefit not a bug?
For BTC/BCH; you can spend unconfirmed coins unlike Monero. However its fairer to compare Coinjoin vs Monero; Coinjoining often takes longer than 20 minutes.
You can have multiple outputs to mitigate problem like using pocket change as you said and also you can pay to multiple addresses at the same time.
With both BCH and XMR the key is to have multiple outputs in your wallet. Then you can spend as you wish.
The whole issue is just lack of knowledge on the part of users.
BTW, Bitcoin Cash uses CashFusion, this is an upgraded version of CoinJoin beyond anything that is available on BTC or anywhere else.
