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.
absolutely right. the results certainly affect confidence in the ICO. After trying and can produce will certainly more and more trust in ICO. indeed sometimes there's a scam, but the revenue is much larger.
