A hacker has tricked Experty ICO participants into sending money to the wrong wallet address. The email users received was not sent by the Experty team, but by a hacker. Experty is preparing a blockchain-based VoIP calling system, where users pay with cryptocurrencies instead of money. The ICO was supposed to help the company raise funds (in the form of the cryptocurrency) to build this service. The scammer made at least $150,000, possibly more than $100,000.
