please help me what build is profitable with free electricity?
with free electricity you should be good , the question is, is your ROI .
Dont forget about a few very important things :
None of those calculators you are seeing on the web can tell you what's coming tomorrow , months later or 6 months later !
Those calculators telling you about today , at that moment when you typing in your information !
No one can tell you how much profit you going to be able to make !
No one can tell you it's going to be profitable for you or not !
No one can tell you for sure what's going to happen with cryptocurrency ,
....price might going down or up ,
....difficulty is going up as more and more ppl get into mining ,its mean you going to mine less and less coins ...
