The vulnerability let unhealthy actors manipulate the trade with out it noticing, apparently for years, and swipe buyer funds all of the whereas.
In consequence, 850,000 Bitcoin was misplaced—nearly 7% of all Bitcoin that existed on the time. This was price $475 million on the time, however at at this time’s fee this may be price over $97 billion.
Whereas struggling the assault, the trade went offline, inflicting Bitcoin’s value to dramatically drop. Buyers grew indignant and demanded solutions. Karpeles then stated that the trade would “discover a resolution.”
