Other places where large scale crypto mining is done is Washington
State in the US, where industrial users can buy power for about
$0.04/Kw. Iceland, where low power costs are combined with cheap
cooling. Various pockets of the former Soviet Union, similar to
Iceland (cheap power and cooling).<br>
<br>
If you can't get power for less than about $0.04/Kw you will be
competing with those than can. Crypto mining is competative by
design and margins are thin. I would look into coins that use memory
intensive algorithms.<br>
<br>
If your analysis is strictly financial you also have to consider the
opportunity cost of not simply buying crypto with the money that the
mining rigs would cost as the major coins are rising in value vs
fiat currencies currently.<br>
