We are attaching a Nostr identity to an on-chain address. It doesn't matter if it is reusing an address or creating a new one every time (which will also be attached in a Nostr zap event - and thus de-annonimizing it). Anonymity is gone for anyone touching any of those Nostr addresses and all of their Nostr connections by definition. And it's kinda the point of zaps. We want to publish our transactions for everyone else to see. If you don't want those coins linked to other coins you might have, don't transact with them. Keep Nostr wallets to only talk with other nostr wallets.

Monero addresses cannot be re-used. Bitcoin hinges on the user knowing what they do, which they dont.

Suddenly money is not fungible? A Satoshi earned here should be as usable as a satoshi earned there. The more identities and off chain data associated with utxos, the worse fungibility becomes.

The fact that "normie user dgaf" is exactly the reason why non-normie users should give a fuck and why devs shouldn't push harmful implementations, practices, or defaults.

@npub1tjkc...s9w3 Since you boosted/reposted this note, did you notice what is going on with onchain zaps recently here? Amethyst and Ditto have implemented these, and they use your nsec as a Bitcoin wallet, which causes address reuse with all its consequences.

Good idea to use always new address Everytime . It’s more privacy.

Sure. That is why XMR obfuscates addresses in transactions. 😉
