Not sure what you are asking exactly. In regard to the markets I use Blockfolio and you can enter the coins and exchange you want to watch in there. Coin Gecko is also great however it is about 30minutes behind so I don't use that for live prices. In regard to information you just need to read the blogs and watch videos to stay in touch with what is hot.

I mean~
I am looking for a way to know, at every moment, how many ethereum people have invested in the ICO.
Thank you.

You have great content, you have a new follower.

I am fairly sure you can check the progress. You can use EtherScan - Example for EOS - https://etherscan.io/address/0xd0a6e6c54dbc68db5db3a091b171a77407ff7ccf

Thank you. It is exactly what I was looking for.
