I just sent 1m sats ($300 USD currently) from nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq to my nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct node in about 4 seconds and paid a whopping 4 sats (or $0.0009 USD). You tell me any financial institution who can do it that fast and cheap.
