Can you imagine how many top-level exchanges are asking for listing coins? This is a huge amount. I very much doubt that these amounts are justified and will bring the result adequate to such expenses. It is better to spend the money on the development and development of the project.
I heard that Binance promised not to take a fee for listing coins, but to select new coins according to the criteria for technical innovation and prospects. Team Ichiba did not try to apply?
I think that it is very difficult or almost impossible to get on such a stock exchange, especially for free. Those coins that pay and there is no sales volume delist from it. And newcomers will have problems with this.
