2021 is the year of gems. If you want to read about a real dark horse, then here's my advice - pay attention to such a project as ApeFarmer. It seems to me that over time this project will blow up the market because it is more relevant than ever in our time.
It is not a real gem, but a fake gem that is only made to be more attractive when viewed from the outside while the original is not, because there are many other projects with almost the same concept as that one and also still better than that one.
