It caused by the majority of those projects are new project. Remember when we can choose the right project and we will get a lot of advantage from there. Remember about jarvis network token and it has been paying a lot of money to the hunters.
instead of just new projects, but sometimes there are old projects that have not yet entered the popular market, for example like easyfeadbeck they have made sales at tokpie and almost 1 year more have not yet entered the popular market as well, even though their project is in my opinion an active project
reason for this is because listing also need to be paid by owner of the project and if you want to list in popular exchange you need to also pay higher amount than normal listing from other unpopular exchange.
At the same time popular exchange can't decide to.list their coins without reviewing a project, its not that easy to be listed there.
This is a good thread to read up about exchangers and its corresponding fees including listing:
You can actually list out your project with Binance but that would really be a hard stuff to be done yet lots of things to be considered first for you to be selected.
We know that most projects now are shit and if they do get listed they do end up on shitty projects.
