where no third party has a hand and there is no chance of losing money.
I wouldn't go that far though. A lot of people have lost money getting their funds stolen one way or another.

I agree a lot of people had lost money in the past with bitcoin son examples of how this happens:
-They lost their private key
-They invest ina ponzi
-They got hacked
-The service where they was holding their coins got hacked or run with the money
The fact that someone has thousands of dollars worth of crypto in their wallet and not have a backup of their private key stored somewhere, or even written down, is mindblowing to me.
