Thanks for good points, but many projects that turned to be scams had very good social media account and seemed legit too..but I agree that if they deliver information regularly it add credibility.
You should analyze the team behind a project. If they have a noce background with legit information, it is a good sign for a project. Also, you need to follow their social media account which give you information daily or weekly. Suddenly changing posting routine or being disappeared is a sign they might exit scam
Low coins are very charismatic but the risk is pretty high. So be careful whenver you want to invest your money to them. Money management is also a factor heping you reduce the danger. More time is needed to check several projects
