Just speak for yourself bro, the truth is that if you have been in this space for a long time, and you have not heard about those coins you have mentioned, then it is possible you have been hiding in a hole ever since for you not to have observed what is happening in the space you are in.

These are projects that have gained huge ground and most long term investors that have been here and even some new investors who have spent some few months, one way or the other, must have come across these ones that you have mentioned. So the fact that you are saying they are not as famous as the other altcoins, is even the weird thing here.
