Indian Exchange Loses $3.3 Million

Coinsecure, an Indian bitcoin exchange, announced on its website that 438.318 bitcoins worth about $3.3 million were stolen from the service after a single employee exposed the exchange's private keys. The private keys, which are pieces of cryptographic code that move blockchain-based digital assets, were made public by chief security officer Dr. Amitabh Saxena, Coinsecure said. The exchange said Saxena claimed he was attempting to distribute bitcoin gold to its customers when he exposed the keys.

Louisiana Mayor Suggests ICO

Mayor Robideaux suggested Lafayette launch its own cryptocurrency and sell it through an ICO. He said the city could use the funds to "develop solutions targeting government inefficiencies, and, more importantly, alternatives for financing public infrastructure."

The new law is geared toward setting up more formal regulations for cryptocurrency in order to attract crypto investors, traders and businesses to the island. The rule would require exchanges, wallet services, payment providers and cryptocurrency businesses to retain customer information. Bermuda's Minister of National Security Wayne Caines told local media this week that Bermuda "can't keep up with the amount of people who want to come to Bermuda ... It's actually phenomenal."
