For me it is easy to trust if you can see a good result as well as a good feedback. When I first knew ICO all I know is one way of being progressive that can lead to become successful. Their are different ICO to join through out the way. It is up to you how are you going to find way to join and extravert yourself to the highest rank to be better too.
Same here, I got your point it means it is really easy to identify if the project or the ICO is generated into success and also the team has the capable of doing the task without hesitations it means they are a good voice.
