Imagine you are living a big family house because you have no choice and you got to invest some money in Bitcoin and store them in a hardware wallet, then you have a safe beside your bed where every can pass by how will you make sure no one goes near out?
I recognize the need for secure crypto asset storage measures, but if you live in a house where you have to hide the HW device in a safe to protect your funds from relatives, then it seems to me it’s time for you to move out and stay away from such relatives.
Okay, let’s say you keep the hardware wallet in a safe, but what about the seed phrase? Do you keep that in the safe too? If so, what is the point of this HW device?
In reality, without the pin code, even your relatives wouldn't be able to access the hardware wallet's contents. They wouldn't be able to access the contents of the safe either, since they wouldn't know the password (or have the key to the lock).
A friend said he had to set up an alarm system in the locked safe so that he can be notified on phone when someone opens his safe where he kept his hardware wallet.
I must admit, this is a very useful thing. I would add this as well.
I don't know if this is a good idea but I will like people's opinion about this, if you are living in a crowdy house basically a family house how do you keep your Bitcoin wallet safe?
Essentially, you are doing the right thing by keeping the hardware wallet in a safe. You should also add a safe alarm that sends notifications to your phone, along with a camera pointed at the safe so you can see who is trying to access it. You could also make access to the room itself more difficult (e.g., by installing a lock). That leaves the question of how to store the seed phrase safely and discreetly - either within the house, on the property, or perhaps at an entirely different location.
However, don't overlook the most vulnerable point: yourself. If your relatives were to conspire to gain access to your assets, they would target you directly. If you perceive a potential threat (and possess significant assets) it might be best to simply move to a different location.
At the same time, by ramping up security measures (safe, alarm, camera, room lock), you will inevitably arouse the curiosity of your neighbors; they will become very interested in what exactly you are hiding and just how much of it there is.
