William Robinson shares a report from The Economic Times: Nearly 438 bitcoins, worth nearly $3.5 million, were stolen from a top exchange firm in India in what is being billed as the biggest cryptocurrency theft in the country so far. The exchange, which has over two hundred thousand users across the country, found that all the bitcoins that were stored offline had vanished. It was later found that the private keys -- the password that is kept by the company and is stored offline -- were leaked online, leading to the hack. The company tried to trace the hackers, but found that all the data logs of the affected wallets had been erased, leaving no trails about where the bitcoins were transferred. Coinsecure, a Delhi-based cryptocurrency exchange, is accusing its CSO, Amitabh Saxena, of siphoning off the money from the firm's wallet. The exchange is urging the government to seize Saxena's passport, fearing that he may leave the country.
