Former stockbroker / Wall Street fraudster Jordan Belfort determined ICO (Initial Coins Offering) as "the greatest scam". A new form of fund-raising, ICO is, in fact, the sale of cryptographic tokens by start-ups in exchange for financing with the help of crypto currency, such as bitcoin and ether, to attract funding in the early stages. Earlier in September, the project of decentralized data storage Filecoin set an ICO record, raising $ 257 million. According to one tracker, the collection of funds by the ICO method in 2017 exceeded $ 3 billion.
