Widening the group of those affected by last week's hack, Bitfinex said customers will lose just over 36% of the assets they had on its platform but would be compensated for the losses with tokens of credit. Hackers took 119,756 Bitcoins (COIN, OTCQB:BTCS) from the Hong Kong-based exchange Tuesday night, stealing $72M in the second-biggest breach of a crypto-currency exchange ever. The hack accounted for about 0.75% of all Bitcoins in circulation.
