I recently thought about my collection of BTC buttons, tie pins, etc., and wondered if Id ever wear one again. I used to wear a BTC baseball cap everywhere I went, including on stage. That was before we started worrying about $5 wrenches.
Well, on the optimistic side, there must be a lot of people out there with fairly low balances (or even the ETFs now) enough that the prospects for a potential robber might not actually look that great. On the other hand, if they know some (but not a lot) they might assume you're carrying all your stash on your phone.
If you're driving around in a Lambo with a Bitcoin wrap, all bets are off, of course.
In the end though, need to know seems to be the best policy and the number of people who need to know is somewhere close to zero.
A long time ago, in one of my classes (I was teaching digital electronics to military trainees), I offered to give $1 in Bitcoin to anyone who cared to learn about it. A few students were interested, especially the females. I asked them to invest one month's worth of their allowance (paid to them monthly by the military academy) in Bitcoin. This would have gotten them a good amount, maybe close to 0.5 BTC at the time. But no one did what I suggested. Not to my knowledge at least.
Of the two people I gave trial sums of Bitcoin to, both lost their phones (even though I had told them specifically to make sure they backed up their wallets). One found their lost one again after a search. I also gifted some but having learned my lesson, I gave a paper wallet and kept a copy of the private key.
