A friend of mine runs a small local charity and she's given everything she has to it. She takes no money and has used most of what she had to help support vulnerable people.
I've introduced her to the idea of fundraising via geyser and using social media including and especially #nostr to raise funds.
She's not a Bitcoiner yet, but she will be.
She also helped raise money to help me after the fire that wiped me out in 2020, so I owe her.
