That is exactly what all teams should do. There should always be a person who will answer questions from investors in topics. There will be answers, there will be good amounts of investment.
I would say otherwise. Answers from the project representative are a good sign for the investor. But this is not a guarantee of satisfactory ICO collections.
I agree. But the fact that there is a dialogue with the representative of the team is also good. This means that developers will listen to users and potential investors.
