what are the possible reasons why tokens takes too much time before getting listed on exchange.
If only for slisting in the market carelessly, or in other words, a market that has a low transaction volume actually could have easily done it. However, the owner of the project does not want their coins to be just a display in the market without any large transactions taking place every day. The problem is to be able to list on a rather good market that cannot be done haphazardly. There are requirements that must be fulfilled by the owner of the coin. The exchanger doesn't want to slash new coins in vain.
