Usually it takes 2 months before seeing the increase but keep in mind that not all altcoins especially those which are newly listed, are having price increase after being listed on different exchangers so we can't really tell. It might be the reason why manybpeople are choosing to sell immediately upon recieving because they are not expecting that there'll be more to come since uncertainty is present on the market price of cryptos.
No one can really say as far as I know, other coins rise pretty quick like DocAcademic. It rose like a few days after its listing. So its hard to say specially at this bearish trend.
It can take as long as you want. Sometimes it takes a couple of days, sometimes you have to wait a few months or years. And it happens that the coin never reaches the price as during the ICO because the team is not working on the promotion of the project.
Exactly, because most of the times, investors are only willing to invest if the coins is already listed that's why it just might take couple of days. But there are instances that eventhough it has been listed and promotion of the project is still on-going, the price didn't see any good unless after a couple of months when pump-and-dump groups do their thing.
