Thank you. It is precisely because of your continuous research and development that Grin has never died. Earlier today, I was chatting with a friend on WeChat voice about the bleak state of altcoins—Beam being delisted from [Gate.io](http://Gate.io), and Grin’s price keep falling. just because I often come to this forum,I know that some people like Cobragrin、wiesche、waynegeorge、Anynomous 、trab、ardocrat、syntaxjak、bruges、Neo-Geo、gig and many other people silence in the forum, I think if there are some people here to contribute for this project, that it is still a good choice to mine or buy the grin coin. At the the time,I also want to thank every reader who comes to this forum—your very presence is part of the Grin ecosystem. What keeps a project alive is not just code updates, but the fact that there are still people connected to each other, watching Grin move forward together. ---
