Lesson; Always back up your seed phrase, password, recovery phrases, private keys that has access to your Bitcoins and wallets.
I think that only happened in the past when bitcoin didn't have too much value and many people didn't have faith in it. But that will be difficult to happen these days when everyone knows the value and potential of bitcoin in the future. I even know many people who only hold a handful of bitcoins but are also very concerned about protecting their seed phrase carefully, let alone those who hold large amounts of bitcoin. Things have changed a lot because the value of bitcoin is huge now.
