I learned to not invest in sales, it's better
to wait listing and to buy when price drops, if I really wish to invest in that project.
This is absolutely true, this is what I learned from my personal experience and I always remember it so that people pay attention not to fall into the trap of fraudulent projects.
So I would advise anyone if they want to buy ICO they should not do that before they are listed on the Exchanges and their price stabilizes.
