I think you miss the point.
I'm not guessing one particular number. I generate an address and then compare that to 60000 known addresses with balances, thus increasing the chance by 60000 on every attempt.
The computer is on for other reasons 24hrs a day, so no extra electric being used.
250 million numbers which is compared to 60000 known addresses with balances every 24hrs!
So if it does get one, it's will have a balance.
I believe bitcrack does exactly this but uses a GPU card.
Still a bit of fun.

It's a nice exercise but a complete waste of time and resource.
Just to give an idea of what number you're searching for...
If you consider all "grain of sand" of the earth is one private address ... and for each of this "grain of sand" you consider another earth with all "grain of sand" you have the idea of a really big number that is much much lower of the total number of bitcoin address!
Please see below some "bitcoin address" that I left in my pocket
after my last tour in a desert
