This should not have happened. But I have a hard time finding any sympathy for cryptocurrency folks. The quote from the article:

"I lost my retirement fund in a hack/Scam when I switched my Ledger over to my new computer and by accident downloaded a malicious ledger app from the Apple store. All my BTC gone in an instant."

Leaves me really shaking my head. If someone has the knowledge to even buy bitcoin or cryptocurrency, I imagine they have enough knowledge to know how utterly crime-ridden and risky of a speculation it is. It's like if someone decides to put their retirement fund into buying bulk illegal drugs and then selling them at a massive markup. Pretty risky, potential high upside, but given they assessed and then accepted the risk, hard to feel bad when they get robbed of all their drugs and lose their retirement funds.
