Friends a question to see who guides me please. I am new in the world of mining and I want to advance a little more here. I have seen some of these devices Gekkoscience 2pak ..... but nothing concrete in itself. I would like to know if it is currently feasible to buy some of these equipment and put them under mine. Which currency is more feasible to mine, since these are something old and for bitcon they no longer serve. What software should I install that other equipment must be purchased? Please, if someone can instruct me in this ...
