This all sounds pretty bad TBH.
Using your Nostr Identity (you know the thing people keep raw dogging into apps) as a bitcoin key creates a perverse incentive for nostr app developers to try to skim keys.
Easy rugging AND your key might already be exposed and no one cared enough because you don't post mamy events or whatever.
On top of that using a single address creates all kinds of privacy issues and key revelations from address reuse unless it implements stealth addresses, which upon first reading, this doesnt do. Then not only is your Bitcoin rugged so is your Npub.
NACK
