How much does a Gate.io listing cost?

Can anyone provide insight into the costs associated with having a cryptocurrency listed on Gate.io? I'm particularly interested in understanding the financial implications for projects looking to expand their reach and tap into the platform's user base. Are there any upfront fees or ongoing charges that need to be considered? Additionally, is there a standard pricing model or do costs vary depending on factors such as the project's size, popularity, or trading volume? Understanding these details would greatly assist in making an informed decision about whether to pursue a Gate.io listing.
