I believe, correct me if i'm wrong, the question in the LTT video was more a general questing. Is mining profitable?
Is gold mining profitable, not what tools are the best for the job. But rather the act of mining itself. If i spend time mining for gold, silver,.. will i get some actual profit? or will i just waste time and effort? Are these cryptocurrencies actually worth mining?
and for the selection of the tools, yes, i believe they just took whatever they had available and suited their own preference.
