值得投资加密货币吗？

Well, the idea of crypto farming is worth it if you are willing to take the little profits that comes out of it because its not going to be a huge profit unless you are using a huge capital. But its better than risking your crypto to other methods that are not guaranteed to make you profits. Farming can make you profits depending on how much you inject into it but certainly you need to research for the project you want to farm and make sure it's what you want to do.
