Generally without KYC people are not allowed to participate in the IEO and that minimizes the number of scammers.But the main thing is that it is being having other effect for example good exchanges boost up the price of their own token and this is going to have a negative effect in the long run.Because generally in these case bots and exchanges do not allow people to participate and when listed in main exchange same phenomena PUMP and DUMP.Its better to stay away quite risky at present.
We need to understand the bigger picture here.Manipulations are being going on,and soon with the new DEX platform many projects are already migrating.So have to wait and watch.
