Not until we start seeing crypto scammers get arrested for real many new investors won't join,I have friends that won't join crypto because of scammers running away with ICO funds forever ,no way to arrest them and get the funds out of them,the few news I read about getting some scammers is not enough ,the more there is an effective way the less scammers will harm crypto
depending on the country the scammer is located and how the country treats such people or how the country react to such crime. You know in US they take scammers as a very serious crime and will not waste time to prosecute them. So if some countries take this very likely, then you would see a different approach.
