Bad idea to be talking about any of this stuff online or anywhere else information can be harvested from. Advertising you keep large piles of cash at your house isn't a great idea unless you are looking to help your wife out with a large insurance payout when someone comes and puts a gun to your head for that money.

Years ago I always kept cash around "just in case". These days that is just getting too risky. I keep cash on hand in case I need it quickly but I don't keep it anywhere associated with me.

And as far as advertising publicly online that you are doing something that could be considered illegal again isn't really the smartest thing to do.

Bottom line "cash is king" but remember talking about it isn't smart. Kind of like carrying a gun - no one needs to know you have it until you need to use it.
