That question is as impossible to answer as "if I started an apple orchard how profitable would that be".
And likewise if you assume values for the cost of apple seeds land, see how many apples you can grow given a certain amount of time - and the value of apples could very well go down - but for the sake of demonstration you can also calculate a very rough estimate of apple orchard profitability, no?
Assume a perfectly spherical cow, emitting milk equally in all directions...
Unless you have free/ very cheap power, is likely not worth your time.
