Hackers may have gotten away with $60 million worth of bitcoin after a cyber attack hit the cryptocurrency mining platform NiceHash. Users highlighted the cyber breach on Reddit and Twitter Wednesday, with some saying they could lose hundreds of dollars.

NiceHash lets people offer computing capacity for bitcoin miners to mine digital currencies. Cryptocurrency miners work out complex mathematical equations to add cryptocurrency transactions to decentralized public ledgers called blockchains.
