It never happened to me over decade save for small charges made on my credit card. If someone breaks into your major trading account and empties and the amount is far exceeding the FDIC limit of 100k$ how else can you mitigate the problem? This was never an issue when i was struggling student and earlier yrs on the workforce after graduation but situation has changed drastically recent years. I have major trading account one is reaching 140k usd and other one 401k approaching 500k usd.
SIPC coverage - FDIC would only protect a bank account attached to a brokerage account. Visit the SIPC sight as it's fairly murky if your account is emptied at a firm NOT going through liquidation. https://www.sipc.org/for-investors/when-sipc-gets-involved
