My grandmother sent me Bitcoin. She'd 94.

Yesterday I discovered $100 worth of sats deposited into my wallet from an unknown address. I made nothing of it given. My wallet address is posted on social media sites and I assumed it was an anonymous user leaving a tip. Fast forward a few hours later and Grandma calls. Traditionally she posts me a birthday card with a bit of cash tucked away but last year someone in the postal service decided to help themselves. I told her for future reference its not safe and I'd much rather she just calls to wish me well. Turns out, she did call to wish me well. She also purchased sats and had them sent to my address. SHE'S 94 FFS!
