Bitcoin Mining Costs (potential floor?)

Bitcoin Mining Costs (potential floor?)

My calculations - derived from the sources given in the links below:
A Minimum Price for 1 Bitcoin (Intermediate time-frame) of ca. USD 7,500
(Status: 21st April 2018)

Searching for an intermediate floor for the Bitcoin-price may lead ones research to the obvious input costs for the participating Bitcoin-miners. The Keyword here being: "electricity costs". 

The primary ongoing cost for bitcoin production is that of electricity, measured in dollars per kilowatt-hour (kWh). Of course, different regions of the world will consume electricity at their local rates (which may vary by customer type, power generation source, and time of day) and in their local currencies.

Taking the data from following sources (see links below) I , Ralph Gollner, made several computations which often led to that similar result (range USD 7,350 - 7,500 = 1 Bitcoin). But please take my computation-result as an idea only; The cryptocurrencies-Universe is highly volatile and could lead to the total loss of ones investment!
