There has been some talk in chinese twitter that BeiJing police could (in theory) order the biggest 3 mining pools to do an reorg to get the stolen coins back. So fragile the bitcoin network currently is
That should've happened minutes after the hack if that was the case. This is a scenario in which you have to act quickly. Otherwise, someone's gonna be really damaged from this theft.
If the hacker manages to put their coins in a coinjoin/mixer and spend the BTC and BCH on stuff and then the reorg happens, the products will be delivered basically for free to the thieves and a LOT of Bitcoin users will be affected.
Possibly even the reader of this reply, if they had a BTC transaction after the hack and part of the funds (or the entirety) comes from one of the many addresses the hacker had.
The Beijing police won't do shit. Ordering the pools to do a rollback would affect even the largest companies in the world and a reorg will come with a cost. Binance had a $40M hack last year and the reorg idea came up too. However, Changpeng Zhao from Binance tweeted out
saying it's a bad idea for a good reason.
First thing that came up in my mind when I read "reorg" in your post was the credibility of Bitcoin. If hacks would lead to the reorg in order to reverse them every time, it would literally be manipulating the blockchain. If so, then
how will the miners ensure me they are not going to do a reorg with malicious intentions behind it? I would personally start becoming skeptic and doubt the future of BTC if we ever head that way.
If the police can
order that, then it means they can also order the reorg when I spend my BTC in a way they consider suspicious, if I go through a mixing service or, worse,
they can seize anyone's funds that way.
There are too many consequences. It's just not worth it. If one is dumb enough to not secure their MILLIONS, then it's their fault. Nobody will reverse time in the Universe if you leave 100kg of Gold uncovered in front of your porch.
