Could you elaborate on the concept of Aevo farming? Is it a specific cryptocurrency mining method? If so, what sets it apart from other mining techniques? Are there specific hardware or software requirements? How profitable is it compared to traditional mining methods? Additionally, is Aevo farming sustainable in the long run, considering the increasing difficulty of mining and the potential environmental impact? Lastly, what are the risks involved in participating in Aevo farming, and how can one mitigate those risks? I'm interested in understanding the intricacies of this process and how it could potentially fit into my investment portfolio.
