Yes, there are many scam projects. But there are still good projects ongoing. Mostly ICO prices very small. so if you invested in a good project still have a chance to raise your money. I just following the ETHA project. They have a good project idea and a good team. Another thing is their bounty managers are trusted. So I believe this is a good project.
Scam projects meaning earning money but it is not the investors that will going to earn instead it is directly the team who brought the project. Take time visiting the scam and accusations section, there are many projects being mention as scammer. ICO is just like robbing a bank in an easier way without forcing you to take your money. They just collect it offering you
