When you’re talking about 8 billion dollars, it’s easy to lose sight of the fact that “a huge part of the shortfall was found” means that billions of dollars weren’t.
One concrete claim I found is that many BTC holders might get paid back in USD at the then-price of the coin, which is ~$16K. Bitcoin is currently at ~$65K, which indicates that they could have lost up to 75% of the underlying coins. Just to be clear: this is not the same as being made whole.
