The situation that you have described does not necessarily have to be a harbinger of failure. The team may need more time - this silence and no reason to worry ahead of time.
Can you be calm if after the end of the ICO in which you participated the team’s activity dropped to zero and there is no information for 6 months?
Having invested money in the project, I would like a full report from the team, especially at such an unquiet time for ICO. The silence of 6 months does not speak in favor of the viability of the project.
Here the ANN thread is very active. There are a lot of news from the project. The team continue to promotion the project, has a strong marketing campagn and continue to depevop.
There cannot be a general characteristic for all projects for 2018 based on panic. With regard to the ROMAD team, it is clear that the project continues to move forward and investors expect to complete without experiencing panic attacks and ignoring.
