Yesterday I lost 11 BTC from my Bitcoin Core 25.0 wallet. The wallet wasn't open at the time. I don't know how it happened. Lots of emotions right now.
I am sorry for your loss, be it story or reality. But I want to ask you why you put 11 BTC in a careless wallet. 11BTC means huge amounts of money. Why don't you put a strong hardware wallet offline? People will learn from your loss but your loss will never be recovered. Your wife may not have done such a thing. You may have given your wallet seed phase somewhere.
It's sad to think even with 11 BTC holdings, OP didn't even think of buying a cold wallet to protect his investment. It's a huge amount of money, and shouldn't take it easy when it comes to security. I agree with you, this won't happen if he has a hardware wallet. His wife may not cause a hack if he at least think of the security of his holdings.
If we have 1k dollar BTC then we will think about buying a hardware wallet to give more security to that BTC. Because 1k dollar BTC is very valuable to me. Also I don't access anything like (airdrop join) with this wallet which I use to take weekly payments. In this case how did the OP keep 11 BTC and use that wallet carelessly. In this case I find it very difficult to accept.
