the best way to choose ico is to read the whitepaper, team, and roadmap. You can also visit the ico rating website as your reference.
Don't rely on that website to give you the information that you need to invest in a coin. Read the Whitepaper.
Whitepaper is also very easy to counterfeit and often copied from other projects, even TRON has been accused of copying some documents from other whitepaper. Also whitepaper is just words, it is not the only thing to choose the project
of course, but only from whitepaper we can know what the project is. whitepaper explains anything that investor should know. that's why whitepaper must be read by investor or another stakeholder
in the other side, there are many things that affect on ICO. we must consider others too such as team, roadmap, community, etc
