Having an MVP ready will definitely bring in more investors who will think that the team is determined towards making a successful platform which can be utilized and benefited by the population around the globe.
You are definitely right, also they are late on their first road map so this can cause decrease in investors attention/trust. Hopefully they'll deliver in march(afaik they wrote march in their next road map)
Having such a long road map with long term dates it looked like they wouldn't have this kind of schedule problems. Now I think even they are not sure about when will be the MVP ready.
