Nostr correlates with Bitcoin, but it's an open protocol which even has monero based clients...there is a lot of maxi echo chamber here, it might give you an extremely biased view of Bitcoin, since people like me use monero because of bitcoin's flaws, failure to become p2p digital cash, failure to become fungible which is an essential quality of money, and failure to implement privacy or anonymity.
This is not even discussing all the Epstein blockstream core dev shit. Caveat emptor.
