@tromp. Thank you for the clarification.
@Hueristic. I do not know. What were the reasons for skipping the 4th one. It might be useless?
@U. Grin is not backed by any venture capitalists and investors who are willing to play the Binance pump game. Grin is a community coin being created similar to bitcoin.
Binance will list Grin on their own because it will be necessary.
