u can trust the people that come to your house.
Thieves are not foolish, they are usually smart people too, you know. Even if you don't go about telling them how much Bitcoin you own, but once they know you are a big fish (someone fully into Bitcoin) they will find out the rest of the information they needed.
[quotesince we do have visitors coming to visit us on some regular basis whenever we traveled home from city.
There is this misconception some people have that anybody who owns Bitcoin is rich. Some of them don't know that Bitcoin could be bought in small quantities, they just believe that you won one Bitcoin and above. Technology has also made people more enlightened, I think most criminals know something about cryptocurrencies.
It's a creative concept, but I wouldn't do it for safety and peace of mind since you don't know who would come to visit. Even if you restrict people who will enter your home to just family and friends, they can take pictures in your house and upload or post them on social media. And this could be viewed by the wrong people. Anyway, congratulations OP on your new house and hope you enjoy your stay there.
