My daughter lost 0.5 BTC because a dog stole her phone on a beach in Vietnam
No this is not a metaphor. An actual dog ran up and snatched her phone right off the towel while she was lying there in the sun.
The phone had the wallet app. She never wrote down the seed phrase because she was 23 and thought nothing bad ever happens to 23 year olds on vacation.
We searched for that dog for two hours.
The dog did not care about Bitcoin.
I don't even know how to be angry about it. It's the most Vietnam thing that has ever happened to our family. She cried, I laughed, then I cried too.
Write down your seed phrase. Put it on paper. Put that paper somewhere a dog cannot reach.
That's the whole lesson.
