I don't get it.

So you are saying that i should put my money in a brick and mortar Bank , because it can keep them safe and then you tell because i can't defend against navy seals? Are you serious? You telling me that a physical place were people store large amounts of bitcoins is safer in face of the state than anybodies house? Not even Iraq was able to hold it's wealth in face of the seals .

And bro , not even now you ain't forced to keep your BTC in your house . You can keep them off site , on an usb , a bitbill , cd , just encrypt your wallets and bury them somewhere, and even if you keep huge amounts in house don't tell. Now if you keep a million USD worth of bitcoins in your house and you let people know , the incentive to be robbed is quite higher than the risk unless you hire some thugs. You don't want to do that ? Take your usb to a safe deposit box at a brick and mortar bank , you don't need a dedicated one. The dedicated one has one big value on it's head, It is a threat to the established system so it ain't safe in any way.

My wonder world works like this: If the incentive to do something is big enough then nothing can stop it from happening. Not even the seals or the pope or the queen or any law system. The law system ain't actually protecting you , the law system works by RAISING THE RISK through fines and punishment ,applied AFTER something has been COMMITTED . That is exactly what you are doing by buying a gun . But the best way to protect your BTC is not to brag about how much you have.
