Sending bitcoin on nostr is called zapping. Zaps are integrated into most nostr clients/apps. Do you have a lightning wallet?
Oh ok, thanks 🙏🏽, great explanation, much appreciated. I use a hard wallet to store my $btc Which lighting wallet would you recommend?
For zaps specifically, custodial lightning wallets are the easiest and most convenient. Just keep the total balance low. Wallet of Satoshi, Primal, CoinOS, and Blink wallet are some popular ones. Availability depends on your area. If you want to go a bit more advanced there are self custodial options like Alby Hub and ZeusPay.
