“Unfortunately, there has been a security breach involving NiceHash website.
“Importantly, our payment system was compromised and the contents of the NiceHash Bitcoin wallet have been stolen.
The number of bitcoin stolen has since been revealed: approximately 4,700 bitcoins, or roughly $63.92 million dollars as of this writing.

“In hindsight, NH shouldn’t have kept so much money in a single online wallet,” posted one user on Reddit.
