The next entry on this list is a funny one, albeit a tragic one.
A Russian crypto exchange got hacked in December 2020 and lost complete control of its servers. Sounds impossible in 2020, right? But in the case of LiveCoin, this is exactly what happened. Users came to know about it when they saw this bizarre message upon visiting their website:
The attack seemed to have taken place on December 23, and the hackers not only took complete control of the LiveCoin infrastructure, but they also modified the exchange rates to reflect largely inflated and gigantic rates. The hackers then started cashing out their accounts based on these modified rates, thus making great profits.
Soon after, the LiveCoin platform was taken down and never came back.
