We investors also have our own errors in this too, when we make investment, we forget they have to go through development stage, and then we want them to quickly get inside an exchange so that we can quickly make profit out of them, if they refuse to enter exchange and they continue with development, you see many people frustrating them via their telegram group and already making them feel like they are shitcoins already.
That is why some of them are tempted to get listed on a shit exchange, and then some of them, along the line when they don’t enter shit exchange, while waiting for the time to enter a solid one, they also get carried away along and then forget about the project continuity, but this is not an excuse anyway for people.
Responsible developers will not give any excuses for the project developments. If they really have a good plan to workout with their project, they won't need to rush things out instead they will keep the project in shapes. Even there are some delays due to many factors that influenced the market, they will keep track, which is not bad in the long run.
Being listed to any exchanges, both well-known and those unknown to many, should not be a concern if the team behind is really providing good developing progress. It will continue to survive without any fear from the market.
