Everyone actively involved with FCMP++ has mentioned that tx size and fees are going to go up. Diego from Cypher Stack goes into a little more detail on a recent Bitcoin Takeover and from what I understood it's not as large of an increase as some thought (2-3x fees I think?).

But you're gaining many magnitudes larger decoy size per transaction. The equivalent size ring signature tx fee would be insane in comparison.

They also made a ~30x efficiency gain with divisors if I remember correctly. But not sure how/if that translates to reduced fees.

So FCMP++ is basically trading higher fees for massively better privacy - 2-3x cost for exponentially larger anonymity sets. That's actually a reasonable tradeoff.

The 30x divisor efficiency gain is interesting but you're right to be unsure about fee impact. Efficiency gains don't always translate to lower costs, especially when you're adding complexity elsewhere.

Honestly, if XMR can keep fees reasonable while delivering real privacy, that's still better than Lightning's custodial mess or Bitcoin's transparent chain. Privacy has a price.
