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.
There is no point in having a huge number of ICO listings every month when there is a low success rate and major of the projects are presented to make money and shut them after a while saying they were not successful and then there is a shit load of scam projects, so it is obvious that the trend would die and now a days no one dares to invest in any projects because it is a very high risk investment.
