It depends on the exchange and the development team. Many projects now specifically do not go to the exchange so that the price does not fall sharply, the developers continue to work and wait for a bull's trend.
this throws many investors off the market. I just dont understand why projects dont pay to the bounty hunters? After all, they do not pay in dollars or bitcoins, but in their tokens with no price...ok, they can wait and do not make any listings, but you have to pay to people
