There were too many scammers in 2017, at the moment when the rise of Bitcoin lured many new players to the market. The bear market has driven many scammers out of the game, because after the Bitcoin collapse:
1) many potential investors left the market.
2) Increased awareness of people investing in projects. They began to think more about what they were doing and how it should earn them money.
I do not deny the fact that the ICO market needs rules. But it should not be iron mittens. Everything must be adequate and plastic. It often happens that some investors, by their very nature, are starting to spread incorrect information about the project and accuse of fraud. It is necessary to make sure that the project has the right to defend its reputation and to protect itself from attacks. And since we are talking about the regulation and punishment of unscrupulous projects, then we should not forget about unscrupulous investors.
I say this because I myself have seen how people invest money without even reading WP projects, and then they are surprised at why the project does not develop along the path that they want. Such people are prone to panic and very often begin to spread false information, guided by personal insults. Some of these people require projects to buy trading volumes. But, as far as I know, it is generally illegal.
