Documented cause
BitGrail, an Italian exchange run by Francesco 'The Bomber' Firano, was the primary market for NANO (formerly RaiBlocks). In February 2018, Firano announced a hack resulting in the loss of 17 million NANO tokens worth approximately $170 million. Italian courts later found Firano personally responsible, ruling he was aware of the shortfall earlier and had misappropriated funds. He was investigated for computer fraud and bankruptcy violations.
Lesson
“Single-operator exchanges with no external audits become personal slush funds; insist on proof-of-reserves.”
