In the real cost of running a government if any of them truly wanted to disrupt crypto and make people loose faith and money in it till is disappeared there are dozens of cheaper / faster / easier ways to do it then having James Bond sneak into an engineers lab and change chip design to implement a vulnerability that may or may not wind up in a device that people use to secure BTC / crypto.
The goal doesn't have to be the complete destruction of everything crypto. It could be a way to get to people they otherwise couldn't or punish them. DaveF is making too much noise and has become a threat to our 'national security' (insert other bullshit reason) but we can't get to him. What do we do? No worries, we will make life harder for him. Give us 5 minutes and we will have all of his bitcoin. We've got backdoors for that sort of thing.
At that point they would know
That I had
BTC and what hardware wallet I was using to store most of it
From my discussions here it's obvious that I have a Tangem, a ColdCard, a Keystone and at least one other device.
Which one are most of my funds stored on?
Is it one of the vulnerable devices?
Is it one that I even discuss?
And so on.
There is no such thing as a government not being able to get to someone. It's just that it's not worth the effort.
