If you analyze it wrong, then participating in the presale you can not know whether the project we are participating in will succeed or not and, as you said that it will indeed experience high risk. But at this time, it must be admitted that all new projects not can succeed because the market situation is not on the side of every new project, therefore if possible avoid every new project that you will participate in, and it is certain that it will not work well.
Actually, all successful projects, started from "new projects" when they were just launched... and as usual, that the presale period or when the project has just been launched, it will have a high risk... the possibility of success is smaller because we ourselves see that there are so many projects that even fail completely when they finish selling tokens...
The point is, the younger a project is, the greater the risk that must be prepared to face... sometimes even though we have analyzed the project we want to invest in well, it still ends in failure, because there are so many possibilities that occur when a new project is first launched... it is natural for developer planning not to go according to the roadmap, because sometimes we see sudden changes in plans because there are certain obstacles...
