The second major theft of cryptocurrencies to take place in recent days. The ‘warm’ or ‘hot’ digital wallets are usually based online and designed to allow users to access their cryptocurrencies more easily, while ‘cold’ wallets are offline and harder to access and therefore usually more secure. Leading Japanese cryptocurrency exchange Liquid has been hit by hackers, with almost $100m (£73m) estimated to have been stolen. Liquid has said that it was tracing the movement of the stolen cryptocurrencies and working with other exchanges to freeze and recover the assets. Is someone trying to kill the crypto industry ?
