Monero people are often earliest Bitcoiners 2009-2012. So they are naturally ahead of the curve.
Stats also show that the fastest growing group of active Nostr users are Monero Bros. If you like it or not.
Monero is a project that is built on Bitcoin research. RetoSwap is a project that hasbeen built on Bisq tech but perfected it.
Monero people are not shy taking the good stuff from Bitcon and improving on it in terms of anonymity, privacy, decentralisation (p2p mining) and permissionless censorship resistance.
