6 billion in fiat is too large a figure to be irreversible. Do you have any examples?

A similar incident would be the 1Billion robbery of the Bangladesh central bank

Most of it was stopped and some was even recovered but $66Million is still lost 10years later .

In both incidents protection are reliant on the authorities to minimize the damage ; tether and circle able to freeze tokens is not that different from the traditional finance doing it.

Crypto is only reinventing structures that evolved in every financial system over time.

Overtime they are going away from their founding theme of decentralization . Exchanges and stable coin issuers who can freeze wallets and coins are by definition centralization ; it is worse though as these organizations are less transparent than banks with less accountability

Most of the billion was frozen though if it was not frozen in time it would have probably evaporated just like these bitcoins getting into mixers.
