Don't tell anyone about what you are holding , just don't talk crypto with anybody .
Even if you trust them , they can tell someone and that is how it goes.
Just pick one person you really trust that in case something happens to your coins aren't lost.
If you hold a big amount maybe make a separate wallet , in case stuff like this happens you just give them a small amount of your stash.
But stuff like this will happen more and more as crypto gets more populair , so be safe.
