This is just another reason the idea of "lost coins" is el stupido. The ONLY person with the rights to move bitcoin is the holder of that (those) private key(s).
Period.
And it is their right to move them as they please. Even if it frightens people, or means they are rich, or crashes the price. Or proves they are Satoshi, or ANYTHING. PERIOD.
I am not scared. I still have the keys to my coins.
I suspect the vast majority of the “frozen” coins are not lost or abandon
pretend that the number is 4 million coins 2.4 million would be by long term holders not lost and movable. much as the ones above were just done.
It all an exercise in imagination when we are trying to guess 2049-2059 btc rules and decisions.
realistically I have 20 years left to live. based on family male history 77-86 years old is a common death age for men.
