> increase the fee of a transaction after the fact Someone should have volunteered to help the Pineapple Fund do this instead of switching to Bitcoin Cash (or maybe this is what "Child-Pays-For-Parent" is, and it cost too much). https://news.ycombinator.com/item?id=15995391 >> Since this created a series of unconfirmed transactions, we had to do something drastic: use Child-Pays-For-Parent with a very significant fee. |

Yep, this is what that means. The downside is that the 'child' transaction doesn't just pay for the 'parent' transaction, but also for the 'child' transaction itself. If you make the child transaction a really complex one that draws from many parents, that transaction becomes larger (in terms of bytes) and thus becomes more expensive.
