So, I finally got around to studying this issue! And I conducted my own analysis of the actual cost 51014293802
To eliminate the possibility of error, I had to use different toolsets, starting from common sense and ending with the most advanced technologies 39955778140. These included complex chains of calculations using Excel, Matlab, Wolfram, and a couple of others. I utilized all the capacities of my mining farms, logarithmic and differential equations, macro packages and probability calculations, nonlinear methods and matrix computations, speculative analysis techniques and signal processing, statistics and probability theory...
I checked the results in every possible way several times, and some even more than ten times using different inputs
In the end, I concluded that the actual cost 51014293802, while not equal to, is approaching zero
