A conspicuous sign on your house is the worst, imo, because your house is always in the same place, and you have to be out of it much of the time. Easy to target because the attacker can do a lot of recon and there's nothing you can do about it.

The risk is a lot lower with personal clothing, because unless they tail you, they're not gonna know where you live or anything about you. And no one is gonna just tail a random, even with a bitcoin shirt, because they don't know where you're going, how long it's gonna take... the reward is not worth the risk.

Bitcoin signs on businesses -- businesses are always at risk of burglary, but I think most robbers would know that the business isn't gonna keep their bitcoin wallets/keys inside the business place itself. Same is not true of homes.

Also, for business there is a good reason to advertise that you accept Bitcoin. But I don't see a good reason for your house advertising "A bitcoiner lives here"
