In this case my opinion is that anyone who wants to invest in new projects so my advice is that first see the project whitepaper there roadmap there partners etc all important thing then if project are strong so invest in this definitely they give profit otherwise if directly invest without any search it's a very risky...
Agree with your point we can only invest in any new project after investigation because blind trust can be full of hazards for us. We can face challenges after learning everything about a project so if we have no idea about the whitepaper, roadmap, objectives and squad of the project then we have to choose old and successful coins instead of diving into new project.
Everyone can invest in new projects without investigation but its a loss of money and trust so after losing due their own mistakes people often says that new projects are scam but they don't remember that they haven't search anything related to project before choosing it so it's not a fault of new project but it's a fault of their irresponsibility.
