I absolutely agree with this opinion,many of new ICOs recently turns out to be either total scam or completely worthless. So many risk to take to invest in ICO. So, investing in ICO is not a good option anymore. Moreover there are already millions of coin that the projects are already developed well. Why don't we just put our money on that well-developed projects?
Or why not just stop investing to ICOs and just go with the normal tokens / coins that are already listed on exchanges?
Doing research is still good enough to know if the ICO is a scam or not that will give you strength on what to avoid.
