I use ICO listing websites.
Now many sites offer information about new ICO projects. Therefore, the competition is large and each platform is trying to get ahead. For me, the indicator of good and quality service is the traffic provided by this platform.
I also take into account the popularity of the platform in different countries.
I watch all the news on such this ICO listing websites:
