In my opinion, you will spend more money on electricity if you keep your wallet open all the time. Perhaps it will be more profitable for you to get acquainted with the master codes, buy and configure a small computer, for example, raspberry pi, or rent a virtual server for these needs. Personally, I liked the cryptocurrency Semux, study it.
Wow, I also support the SEMUX project. I also like this project and I also believe that this project can succeed if you simply rely on the fact that today there are really great opportunities in the cryptocurrency sphere.
