Hi guys

For a long time, one question never ceases to worry me - how do people find out about the listing of new coins even before the official announcement? I constantly learn about the listing of a particular coin from traders, and not from official statements. Yesterday, a friend of mine told me about listings of bnx on binance and nwc on crypto.com, but this information was not yet in their sources.

Perhaps there are some insider resources or groups where all this information is? How do you get that info?
