Keep the cold wallet at home encrypted and only a hot wallet with you, therefore if someone attacks you, if you're forced to, you can give away a low amount of coins.I'm unsure how it works in the US, but if it's possible, get a legal carry, if not, as I said, pepper spray, electric shocker, or a knife.
I'll be getting a new batch of bitcoin knives soon, might as well get those

Well, the bold words may work if you are been attacked unexpected. But what if you were been kidnapped? If you send them a low amount of coin, the robber will certainly know that there is alot more you are holding back, after all he targeted his victim before attacking. Have you thought, what if you left home without your pepper spray, electric shocker or a knife? You don't want to be living in fear all just because you are a bitcoin trader. We all hope we don't fall victim to this new type of robbery but I would still prefer to live a normal low key life.
