I am beginning to think that the telegram was created for ICO marketing but after sales, the support has slowly disappeared.
Their telegram should be one of the best channel to communicate their news and updates, and also to answer the queries of the investors since this project does not just stop at a certain phase and we called it a success, its a long journey going to their big goal and they need a supportive community on that journey.
Happens every time to most ICO projects. After collecting money their activity on social media reduces. They forget that it just the beginning of the long journey. Keeping in touch with people and giving them confidence to trust the project the more is the best way to keep afloat even in bad times
