Yeah I heard that as well, I would've searched my ass off on that dump if that had happened to me. But it never will as I still online wallets for my transactions and bitcoins.
Oo You realize that WAY more bitcoins were lost (to their owners) because they held coins on exchanges, online wallets and such? You really should think that over. Giving your bitcoins to someone other brings always the question up if you get them back. Only when you control the private key and no one other has access to it, then you can say that you are relatively safe.
Sometimes both happen at the same time.
When the exchange accidentally deletes its wallet!
https://news.ycombinator.com/item?id=2828445*lol* Didnt hear of that yet. Unbelieveable. Cold Wallet? Backups on the same drives? Even i have backups on different places and im not even an exchange. Hefty... the worst thing is, you only know when something like that happens that the one you trusted is not the smartest.
I was thinking that hardware wallets are the safest way to protect from such loss of any coin.
For that reason I was looking at getting a Trezor. But that gets me thinking, this too can happen to that too, am I correct? How about having two or three Trezors to span the coins on so you don't lose all your bank in case of hardware failure.
