This one heist of bitcoins is more than the total sum of money stolen from US banks in 2011. (Source: https://www.fbi.gov/stats-services/publications/bank-crime-s...). It looks especially bad because about 20% of the stolen money from bank robberies is recovered, instead of lost for good; I don't know how much of Bitcoin heists are repatriated, but I suspect the percentage is much closer to 0%.
No. Most of it never went out, and much of what did was recovered.
"The Federal Reserve Bank of New York blocked the remaining thirty transactions, amounting to $850 million, due to suspicions raised by a misspelled instruction. All the money transferred to Sri Lanka has since been recovered. However, as of 2018 only around $18 million of the $81 million transferred to the Philippines has been recovered."
