Stock Market
The good news is you'll save a fortune in taxes when the market tanks :)
I can't remember the exact number, but there have been more than a dozen market "crashes" since hmmm 1929, and mkt has always recovered and extended within 4ish months.
Google it, I used to know that .
Look at the chart I posted earlier, note how mkt recovered from donald's tea party.
As mentioned, the brokerages do have software to help protect you, if you have the discipline to use it .
Again. Ignorance is the biggest threat.
And fund managers looking for more commission.
