there is achance for me to guess a key,no matter how small that chance is it do exist
Sure, the chance of you guessing a previously used private key is non-zero, but it is so unimaginably close to zero, that it is effectively zero for all intents and purposes.
There's also a non-zero chance of you correctly guessing the one atom on Earth I am currently thinking of, and this is still billions upon billions of times
more likely than you guessing a private key. There's also a bigger chance of you correctly guessing Bill Gates', Warren Buffet's, Jeff Bezos'
and Bernard Arnault's credit card numbers (again, by a factor of billions) than guessing a single private key.
Dude - you
REALLY don't understand lotteries at all. Of course the chance is
low - but there is a chance!!! Are you fucking dense? - or what?
o_e_l_e_o - I want you to admit, right now, based upon you knowledge of math - that there is in fact a chance that clicking on a page of that key server site could produce millions of dollars. If you don't admit that, you are a liar.
