for newbie i think using ico rating like coinmarketcap, ico becnh and suggest from pro traders is best way to know. like this find high rating from ico rating site, asking to some poeple, you can combine from this case to get action
Yes, for beginners it is better to visit the coinmarketcap site and another coingecko site to better understand and know new projects that are born by developers, but for the ico site because the visitors have started to decline when many ico projects don't clear.
