Many companies in the cryptocurrency industry are facing a series of complaints. Reason: to have sold tokens to investors which would in reality be unregistered securities.   The legal offensive against the crypto industry is massive. Investors have filed complaints against a large number of players. In the United States, class actions (collective actions) thus target 7 issuers of cryptocurrencies and 4 exchanges. And the reason for these procedures is not new. He has even already justified several actions in the US on the part of the stock exchange regulator, the SEC. The complaining investors accuse these companies of selling billions of dollars of unregistered assets in violation of securities laws.
