I heard that many companies started to use ICO not only for collecting funds, but also for a good PR campaing globally. Do you thinks it's reasonable or not?
It is very reasonable buddy. Conducting ICOs have been popular since last year and it continues to rise even though price fluctuations affect the performance. When you analyse many of the ICOs, some are already existing companies who wants to use the opportunity to raise funds as well as go global, so they develop the project and also spread news about them. Others who are not already existing companies also develop the project from the scratch and also go viral as well. One thing I have also realized is that, some years to come the world will be damn full of altscoins( virtually used for so many things online) and that will happen only if these ICIs become diligent with their roadmaps. I joined an ICO last year and after sales we all traded and thought the project was dead. Four months later they actually start the project and the price shot so high than we thought, and as at now people are still using their platform.
