If you lived in a social credit dystopia, you would have a reason to be legit scared. ₿itcoin prevents that. Do as you wish!
With twitter it would be worse, because you wouldn't have proof of what you said before. But on nostr you do have the proof. Anyone can come up and prove what you did say if it is really important. You filt*y editor.
So editing your posts here isn't that bad.
