The project is designed to accelerate the use and creation of solar energy, and its own currency is launched. It claims its overall purpose is to offer a cost-effective and environmentally friendly incentive in solar power generation. But to be honest I don't trust the project and in addition I think the project is abandoned now.
Because when I entered the website of the project, I realized that it was not working, only the advertisement screen appeared. In addition, I could not see any platform where detailed information about the project could be obtained. Only social media accounts are shared up to date, but I think it still does not seem enough to get the information. I also did some research about the project, I came across some users' complaints. What is claimed in the complaints, they claim that the value of the token has risen too much at a time and then dropped and lost money by investing in it. When I looked at the graphics of the token, I can say that I was sure of the accuracy of these claims.
In addition, currently the SIERRA token is listed on only one exchange and there is no circulating supply, moreover, the token has a low value. In addition, it does not have a transaction volume and leadership.
In general, I think the project is now abandoned. For this reason, I think it seems risky to invest in markers.
