A lot can be done if there is a will. But as of now no one cares and the scammers are having a free run. I am afraid that now it is too late to rescue the ICO sector. The number of new ICOs listing every month has fallen to a small fraction of what we had in 2018, and most of the investors have decided not to participate in this sector anymore due to bitter experiences in the past.
A few simple regulations could have rescued the ICO sector, such as making third party escrow mandatory for the projects. But the investors continued to pour in their money in to shady projects, and this actually encouraged the scammers. Rather than those who are behind these scam projects, I would say that most of the blame should fall on the investors. If they had been a bit more cautious, then the situation could have been much different now.
Project developers are not convinced of the sustainability of their coin prices in the market, some of the things that I see are wrong in their post-ico mindset, moreover they have more coins than investors, they must have the confidence to control and not just think about the sustainability of their projects, escrow also only facilitates transactions and Refunds, the team does not look at the price precision to strengthen their project, and from this point most scam sentences emerge.
