yourself in your post indicates the reasons why these three companies have these MV,
- Estimated Revenue
- Monthly view pages
- Registered users
and above all a company ALIVE
the market has never valued the (R), the unfulfilled promise of Mobile App, or the famous "coming soon" much less the number of servers
and on the other hand he has punished the lack of updates, no news, no response on the phone, the lack of response to emial, lack of office, lack of work website ultimately the lack of transparency
I remember that promised the launch of the mobile app in July 2014 for the next quarter and not a single reason for two years late
